WGU C268 Study Guide for EXCEL PA
1. Calculate the payment amount for the loan in cell C15. Reference the cells containing
the appropriate loan information as the arguments for the func-tion you use. Cells C20- C67 in the "Payment" column are populated with the payment amount from cell C15.: =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
- 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. f: =F19*C$13/
3. Copy the Interest amount calculation down to complete the "interest" col-umn of
the amortization table.: Paste down column.
4. 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.: =C20-D
5. Copy the principal amount calculation down to complete the "principal" column of
the amortization table.: Copy and paste down.
6. 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.: =F19-E
7. Copy the balance amount calculation down to complete the balance column of the
amortization table.: Copy and paste down.
8. Calculate, in cell G12, the total amount paid by multiplying the payment amount
(cell C15) by the term of the loan (cell C12).: =C15*C
9. 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.- : =SUM(D20:D67)
10. 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.: =G12+C
11. Assume you have made the first 36 payments on your loan. You want to trade
the car in for a new car. You believe that you can sell your car for $4000. Will this cover
the balance remaining on the car in period 36? Answer either "Yes" or "No" in cell G from the drop-down menu.: No
12. Use the HLOOKUP function to complete the "Hourly Wage" column of table

Information" above table 1 as your reference table.: =HLOOKUP(D16, E$11:H$12, 2,False)
13. Use the AND function to complete the "Time Bonus?" column of table 1. An
employee earns a time bonus if the project's "Hours Worked" are fewer than the "Estimated Hours" and if the work "Quality" is greater than 1.: - =AND(E161)
14. Use the OR function to complete the "Outcome Bonus?" column of table 1. An
employee earns an outcome bonus if the difficulty of a job is greater than 3 or if the quality of their work is equal to 3.: =OR(G16>3,H16=3)
15. 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.: =IF(I16=True, K16*M$11,0)
16. 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.: =IF(J16=True, K16*M$12,0)
17. 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.": - =IF(AND(E16<=C16, H16>1) , "Good Job", IF(E16>C16,"Too Much Time","Poor Quality"))
18. 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 your reference.:
=vlookup(B40,B$16:D$35,3)
19. 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.: =Vlookup(B40,B$16:H$35,6)
20. Use the Countif function to complete the #of Jobs, column in table 3. Ref-erence
the "employee" names in table three as your criteria.: =Countif(B16:D35,G39)
21. Use the SUMIF function to complete the "total hours" column in table 1 as
your range and the "employee" names in table three as your criteria.: - =sumif(D$16:D$35, G39, E$16:E$35)
22. Use the SUMIF function to complete the "Total Pay" column in table 3.
30. Construct a line chart to examine the total annual revenue for Google, Inc.
from 2003 to 2010 (use the data in table 2 - range C19:J19). Format the chart with the title on top "Google Revenue Line" and the years across the
horizontal axis. Do not include a legend. Note: in order for the grading engine to identify the chart for grading, the title must be precisely, "Google Revenue Line" (without the quotes).: Drag from C19:J19 and click on quick analysis. Select on line graph. Click on the numbers and then click on select data. Change the name to the dates of Table 1 =Google!$C$7:$J$7.
31. Add a linear trendline to the "Google Revenue Line " chart.: Add chart element and
trendline and click on linear.
32. Use the LEN function in cell D10 to determine the number of characters in the
statement template in cell D9.: =LEN(D9)
33. Use the SEARCH function in cell D11 to determine the position of the "#"
character in the statement template (cell D9).: =SEARCH("#",D9)
34. Use the SEARCH function in cell D12 to determine the position of the "$"
character in the statement template (cell D9).: =SEARCH("$",D9)
35. 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 cal-culated in cell D12 as the "num_char" argument for your function.: =LEFT(D9,D12)
36. 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 "$" (in cell D12)—ad-justed by adding 1—as the "start_num" argument. Use the difference between the location of the "#" character (in cell D11) and the "$" character (in cell D12) as the "num_char" argument.: =MID(D9,D12+1,D11-D12)
37. Use the RIGHT function in cell D15 to return the text "on:" from the state-ment
template in cell D9. Use the difference between the length of the state-ment template (in cell D10) and the location of the "#" character (in cell D11) as the "num_char" argument.: =RIGHT(D9,D10-D11)
