Marvel Parts, Incorporated, manufactures auto accessories. One of the company's products is a set of seat covers that can be adjusted to fit nearly any small car. The company has a standard cost system in use for all of its products. According to the standards that have been set for the seat covers, the factory should work 1,000 hours each month to produce 2,000 sets of covers. The standard costs associated with this level of production are:
Per Set Covers
Total $41,400 $8,000
Direct materials $3,400
Direct labor $26.40
Variable manufacturing overhead (based on direct labor-hours) $3,400
During August, the factory worked only 1,050 direct labor-hours and produced 2,400 sets of covers. The following actual costs were recorded during the month:
Per Set Covers
Total
Direct materials (7,500 yards) $10,080
Direct labor $5,040
Variable manufacturing overhead $3,400
At standard, each set of covers should require 3.0 yards of material. All of the materials purchased during the month were used in production.
Required: Compute the materials price and quantity variances for August. Compute the labor rate and efficiency variances for August. Compute the variable overhead rate and efficiency variances for August. (Indicate the effect of each variance by selecting "F" for favorable, "U" for unfavorable, and "None" for no effect (i.e., zero variance). Input all amounts as positive values.)
