1. Calculate the payment amount for the loan in cell C15.
Reference the cells containing the appropriate loan
information as the arguments for the function you use. Cells
C20-C67 in the "Payment" column are populated with the
payment amount from cell C15. [34 Points] -
โœ…โœ…โœ…=PMT(C13/12,C12,C11)
2. Calculate, in cell D20, the interest amount for period 1 by
multiplying the balance in period 0 (cell F19) by the loan
interest rate (cell C13) divided by 12. Dividing the interest
rate by 12 results in the monthly interest rate. This formula
is reusable. The interest for a given period is always the
monthly interest rate times the balance from the previous
period. - โœ…โœ…โœ…=F19*$C$13/12
3. Calculate, in cell E20, the principal amount for period 1. The
principal amount is the difference between the payment
amount (cell C20) and the interest amount (cell D20) for
period 1. Construct your formula in such a way that it can be
reused to complete the "principal" column of the
amortization table. - โœ…โœ…โœ…=C20-D20

  1. Calculate the payment amount for the loan in cell C15. Reference the cells containing the appropriate loan information as the arguments for the function you use. Cells C20-C67 in the "Payment" column are populated with the payment amount from cell C15. [34 Points] - โœ…โœ…โœ…=PMT(C13/12,C12,C11)
  2. Calculate, in cell D20, the interest amount for period 1 by multiplying the balance in period 0 (cell F19) by the loan interest rate (cell C13) divided by 12. Dividing the interest rate by 12 results in the monthly interest rate. This formula is reusable. The interest for a given period is always the monthly interest rate times the balance from the previous period. - โœ…โœ…โœ…=F19*$C$13/
  3. Calculate, in cell E20, the principal amount for period 1. The principal amount is the difference between the payment amount (cell C20) and the interest amount (cell D20) for period 1. Construct your formula in such a way that it can be reused to complete the "principal" column of the amortization table. - โœ…โœ…โœ…=C20-D
  1. Calculate, in cell F20, the balance for period 1. The balance is the difference between the balance for period 0 (cell F19) and the principal amount for period 1 (cell E20). This formula is reusable. The balance is always calculated as the difference between the balance from the previous period and the principal amount for the current period. - โœ…โœ…โœ…=F19-E
  2. Calculate, in cell G12, the total amount paid by multiplying the payment amount (cell C15) by the term of the loan (cell C12). - โœ…โœ…โœ…=C15*C
  3. Calculate the total interest paid in cell G13. The total interest paid is the sum of all interest paid in the "Interest" column of the amortization table. - โœ…โœ…โœ…=SUM(D20:D67)
  4. Check to see if the total interest calculation in the amortization table is correct. The total interest paid is also equal to the difference between the total amount paid over the course of the loan and the original loan amount. Insert a formula into cell G14 to calculate the difference between the total amount paid and the original loan amount. Notice the negative sign associated with the original loan amount. This value should equal the total interest calculated using the amortization table. - โœ…โœ…โœ…=G12-ABS(C11)
  1. Use the IF function to complete the "Time Bonus $" column of table 1. If an employee earns a time bonus (i.e., the corresponding cell in the "Time Bonus?" column is TRUE), then "Time Bonus $" is the "Job Pay" for that project times the bonus percentage in cell M11. Otherwise "Time Bonus $" is 0. - โœ…โœ…โœ…=IF(I16,K16*$M$11,0)
  2. Use the IF function to complete the "Outcome Bonus $" column of table 1. If an employee earns an outcome bonus (i.e., the corresponding cell in the "Outcome Bonus?" column is TRUE), then "Outcome Bonus $" is the "Job Pay" for that project times the outcome bonus percentage in cell M12; otherwise, "Outcome Bonus $" is 0. - โœ…โœ…โœ…=IF(J16,K16*$M$12,0)
  3. Use the IF function to complete the "Comments" column of table 1. Display "Good Job" if both the "Hours Worked" are less than or equal to the "Estimated Hours" for a project and the assessed "Quality" of that project is greater than 1. Display "Too Much Time" if the "Hours Worked" on a project exceed the "Estimated Hours" for that project; otherwise, display "Poor Quality." - โœ…โœ…โœ…=IF(AND(E16<=C16,H16>1),"Good Job",IF(E16>C16,"Too Much time","Poor Quality"))
  1. Use the VLOOKUP function to complete the "Employee" column of table 2. Use "Job ID" from table 2 as your lookup_value(s) and table 1 as the reference table. - โœ…โœ…โœ…=VLOOKUP(B40,$B$16:$O$35,3,FALSE)
  2. Use the VLOOKUP function to complete the "Difficulty" column of table 2. Again, use "Job ID" from table 2 as the lookup_value(s) and table 1 as the reference table. - โœ…โœ…โœ…=VLOOKUP(B40,$B$16:$O$35,6,FALSE)
  3. Use the COUNTIF function to complete the "# of Jobs" column in table 3. Reference the appropriate field in table 1 as your range and the "Employee" names in table 3 as your criteria. - โœ…โœ…โœ…=COUNTIF($D$16:$D$35,G39)
  4. Use the SUMIF function to complete the "Total Hours" column in table 3. Reference the appropriate field in table 1 as your range and the "Employee" names in table 3 as your criteria. - โœ…โœ…โœ…=SUMIF($D$16:$D$35,G39,$E$16:$E$35)
  5. Use the SUMIF function to complete the "Total Pay" column in table 3. Reference the "Employee" field in table 1 as your range, the "Employee" names in table 3 as your
  1. Use the SEARCH function in cell D11 to determine the position of the "#" character in the statement template (cell D9). - โœ…โœ…โœ…=SEARCH("#",D9)
  2. Use the SEARCH function in cell D12 to determine the position of the "$" character in the statement template (cell D9). - โœ…โœ…โœ…=SEARCH("$",D9)
  3. Use the LEFT function in cell D13 to return the text "I spent $" from the statement template in cell D9. Refer to the location of the "$" character you calculated in cell D12 as the "num_char" argument for your function. - โœ…โœ…โœ…=LEFT(D9,D12)
  4. Use the MID function in cell D14 to return the text "at merchant #" from the statement template in cell D9. Refer to the location of the "$" (in cell D12)โ€”adjusted by adding 1 โ€”as the "start_num" argument. Use the difference between the location of the "#" character (in cell D11) and the "$" character (in cell D12) as the "num_char" argument. - โœ…โœ…โœ…=MID(D9,D12+1,D11-D12)
  5. Use the RIGHT function in cell D15 to return the text "on:" from the statement template in cell D9. Use the

difference between the length of the statement template (in cell D10) and the location of the "#" character (in cell D11) as the "num_char" argument. - โœ…โœ…โœ…=RIGHT(D9,D10-D11)

  1. Use the MONTH function in cell E18 to calculate the month portion of the "Time Stamp" in cell B18. Copy and paste your function down to complete the "Month" column of the table. - โœ…โœ…โœ…=MONTH(B18)
  2. Use the DAY function in cell F18 to calculate the day portion of the "Time Stamp" in cell B18. Copy and paste your function down to complete the "Day" column of the table. - โœ…โœ…โœ…=DAY(B18)
  3. Use the HOUR function in cell G18 to calculate the hour portion of the "Time Stamp" in cell B18. Copy and paste your function down to complete the "Hour" column of the table. - โœ…โœ…โœ…=HOUR(B18)
  4. Use the MINUTE function in cell H18 to calculate the minute portion of the "Time Stamp" in cell B18. Copy and paste your function down to complete the "Minute" column of the table. - โœ…โœ…โœ…=MINUTE(B18)
  1. In the "Input Analysis" section of the spreadsheet model, calculate the average attendance and sales for each type of product from the past events listed in the "Past Events" worksheet. - โœ…โœ…โœ…=AVERAGE('Past Events'!C4:C103)
  2. In the "Input Analysis" section of the spreadsheet model, calculate the sample standard deviation for attendance and sales for each type of product from the past events listed on the "Past Events" worksheet. (Note for Excel 2007 users: Excel 2007 does not support a specific function to calculate sample standard deviations. Use the STDEV function instead.) - โœ…โœ…โœ…=STDEV.S('Past Events'!C4:C103)
  3. In the "Input Analysis" section of the spreadsheet model, calculate the 95% confidence interval for the sales for each type of product. (You will not calculate a confidence interval for attendance.) Use the number of events (calculated in cell I3) as part of your calculations. (Note to Excel 2007 users: the CONFIDENCE.NORM function is not supported in Excel 2007. Use the CONFIDENCE function instead.) - โœ…โœ…โœ…=CONFIDENCE.NORM(0.05,J7,$I$3)
  1. In the "Input Analysis" section of the spreadsheet model, calculate the correlations between the sales of each type of product and event attendance. Use appropriate ranges from the "Past Event" worksheet for your calculations. - โœ…โœ…โœ…=CORREL('Past Events'!D4:D103,'Past Events'!C4:C103)
  2. The sales for which product type are most highly correlated with attendance? Select the correct answer from the drop-down list in cell L32. - โœ…โœ…โœ…Food
  3. In the "Input Analysis" section of the spreadsheet model, calculate a sales forecast for each type of product if expected attendance at the future event is 18000 people. Reference cell I13 (the attendance forecast) for your calculations. - โœ…โœ…โœ…=FORECAST($I$13,'Past Events'! D4:D103,'Past Events'!C4:C103)
  4. In the "Input Analysis" section of the spreadsheet model, calculate the upper limit for your sales forecast for each type of product if expected attendance at the future event is 18000 people. Reference the confidence interval you created for your calculation. - โœ…โœ…โœ…=I16+J
  1. Which product generates the largest gross profit? Select the correct answer from the drop-down list in cell L38. - โœ…โœ…โœ…Merchandise
  2. Calculate the commissions paid for each product type. The commissions paid are calculated as the expected sales for each product type times the commission percentage from the "Model Inputs" section of the model. - โœ…โœ…โœ…=C15*C
  3. Enter the fixed costs in the model. Reference the appropriate amount for each product type in the "Model Inputs" section. - โœ…โœ…โœ…=C
  4. Calculate the total operating expenses for each product type. This is the sum of salary expenses (yet to be calculated), commissions, and the fixed costs for each product type. - โœ…โœ…โœ…=SUM(C21,C22,C23)
  5. Calculate the profit before the arena fee for each product type. This is the gross profit minus the total operating expenses for each type of product, including the salary expenses (yet to be calculated). - โœ…โœ…โœ…=C17-C
  1. Calculate the number of employees that are needed to work the event for each type of product. This is calculated as the profit before the arena fee for each type of product, times the employees (% of expected profit) for each product type from the "Model Inputs" section of the worksheet. Because you cannot hire a fraction of an employee, round your calculations up to the next whole number. - โœ…โœ…โœ…=ROUNDUP(C26*C7,0)
  2. Which product will require the fewest employees? Select the correct answer from the drop-down list in cell L40.
    • โœ…โœ…โœ…Programs
  3. Calculate the salary expenses for each product type. This is calculated as the number of employees needed for each product type times the salary (per employee) in the "Model Inputs" section. (Employees make the same salary despite the product type.) This will create a circular reference in your worksheet. You will need to change the options in Excel to appropriately account for the circular reference. - โœ…โœ…โœ…=C28*$C$
  1. Calculate the "Net Profit" portion of the "Profit Summary" section of the model by subtracting the arena fee from the profit before the arena fee. - โœ…โœ…โœ…=C35-C
  2. Complete the data table in the "What-if Analysis" section of the worksheet to compare the net profit for various values of the attendance forecast and the arena fee.
    • โœ…โœ…โœ…1.) Find Net Profit

  2. 3.)Values: Summarize Values By Average of Attendance
  3. Which type of event ("Concert," "Sporting Event," or "Other Event") has the largest average attendance? Select your answer from the drop-down list in cell J20. - โœ…โœ…โœ…Concert
  4. Use the event data on the "Past Events" worksheet (range A3:G103) to construct a PivotTable that will calculate the total merchandise sales for events with "Excellent" crowd size. Place the PivotTable on a new worksheet. Use "Type" as a row label and "Crowd Size" as a report filter for the analysis. Rename the new worksheet "PT2" (without the quotes). - โœ…โœ…โœ…1.) Filters- Crowd Size
  5. 2.) Rows- Type
  6. 3.) Values- Sum of Merchandise
  7. For only those events with "Excellent" crowd sizes, how much total merchandise revenue was earned? Select the answer closest to your answer from the drop-down list in cell J23. - โœ…โœ…โœ…$7 Million

  2. What percent of all concerts had a crowd size of "Excellent"? Select the answer closest to your answer in the drop-down list in cell J2. - โœ…โœ…โœ…19%
  3. Use the event data on the "Past Events" worksheet (range A3:G103) to construct a PivotTable to calculate how much more money from total food sales has been generated at both concerts and sporting events than at other events in the sample. Place the PivotTable on a new worksheet. Use "Type" as a row label and an appropriate presentation of "Food" as the "Values" field for the PivotTable. Rename the new worksheet "PT5" (without the quotes). - โœ…โœ…โœ…1.) Rows- Type
  4. 2.) Values- Summarize Values By Sum, Show Values As Difference From Type & Concert
  5. How much more money from food sales has been generated at concerts than at other events, not including sporting events, for events in the sample? Select the answer closest to your answer in the drop-down list in cell J31. - โœ…โœ…โœ…$625,
  1. Use Solver to calculate the optimal number of dozens of product to make. Be sure to save your work. - โœ…โœ…โœ…Solver: 1.) Set Objective: Profit ($C$37) 2.) To: Max 3.) By Changing Variable Cells:
