Marvel Parts, Incorporated, manufactures auto accessories including a set of seat covers that can be adjusted to fit most cars. According to its standards, the factory should work 1,230 hours each month to produce 2,050 sets of seat covers. The standard costs associated with this level of production are: Total Per Set of Covers Direct materials $ 27,675 $13.50 Direct labor $ 8,610 4.20 Variable manufacturing overhead (based on direct labor-hours) $ 4,920 2.40 $ 20.10 During August, the factory worked 750 direct labor-hours and produced 1,500 sets of covers. The following actual costs were recorded during the month: Direct materials (3,900 yards) Direct labor Variable manufacturing overhead Per Set of Total Covers $ 19,500 $ 6,600 $ 4,800 $13.00 4.40 3.20 $ 20.60 At standard, each set of covers should require 18 yards of material. All of the materials purchased during the month were used in production. Required: 1. Compute the materials price and quantity variances for August 2. Compute the labor rate and efficiency variances for August 3. Compute the variable overhead rate and efficiency variances for August Note: Do not round intermediate calculations. 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.
