Questions Chapter 25 (Continued)
(a) Standards are stated as a per unit amount. Thus, the standards are materials $2.40 ($1,200,000 ÷ 500,000) and labor $3.20 ($1,600,000 ÷ 500,000).
(b) Budgets are stated as a total amount. Thus, the budgeted costs for the year are materials $1,200,000 and labor $1,600,000.
(a) Standard materials price per gallon = $2.50 ($2.20 + $.20 + $.10). (b) Standard materials quantity per gallon = 3 pounds (2.6 + .4). (c) Standard materials cost per gallon = $7.50 ($2.50 X 3).
(a) Standard direct labor rate per hour = $14.00 ($12.00 + $.80 + $1.20). (b) Standard direct labor hours per gallon = 1.6 hours (1.2 + .25 + .15). (c) Standard labor cost per gallon = $22.40 ($14.00 X 1.6).
Total materials variance = $1,160 U (3,200 X $5.05) – (3,000* X $5.00). Materials price variance = $160 U (3,200 X $5.05) – (3,200 X $5.00). Materials quantity variance = $1,000 U (3,200 X $5.00) – (3,000 X $5.00).
*$16,160 ÷ 3,200 **1,500 X 2
Total labor variance = $2,050 U (2,100 X $10.50) – (2,000 X $10.00). Labor price variance = $1,050 U (2,100 X $10.50) – (2,100 X $10.00). Labor quantity variance = $1,000 U (2,100 X $10.00) – (2,000 X $10.00).

(b) The unfavorable materials quantity variance may be caused by the carelessness or inefficiency of production workers. Alternatively, the excess quantities may be caused by inferior quality materials acquired by the purchasing department. The unfavorable labor price variance may be caused by misallocation of the work force by the production department. In this case, more experienced workers may have been assigned to tasks normally done by inexperienced workers. An unfavorable labor variance may also occur when workers are paid higher wages than expected. The manager who authorized the wage increase is responsible for this variance.

EXERCISE 25-12 (Continued)
(c) The overhead controllable variance is generally associated with variable overhead costs. Thus, this variance indicates the production manager’s inefficiency in controlling variable overhead costs. The overhead volume variance relates to fixed overhead costs. This variance indicates whether plant facilities were efficiently used. In this case 500 (16,500 – 16,000) hours of plant capacity were not utilized.

(b) The cause of an unfavorable controllable variance could be higher than expected use of indirect materials, indirect labor, and factory supplies, or increases in indirect manufacturing costs, such as fuel and maintenance costs. A favorable volume variance would be caused by production of more units than what is considered normal capacity.
