For the seat covers, the factory should work 2,850 hours each month to produce 1,900 sets of covers. The standard costs associated with this level of production are: Total Per Set of Covers Direct materials $ 42,560 $ 22.40 Direct labor $ 51,300 27.00 Variable manufacturing overhead (based on direct labor-hours) $ 6,840 3.60 $ 53.00 During August, the factory worked only 2,800 direct labor-hours and produced 2,000 sets of covers. The following actual costs were recorded during the month: Total Per Set of Covers Direct materials (12,000 yards) $ 45,600 $ 22.80 Direct labor $ 49,000 24.50 Variable manufacturing overhead $ 7,000 3.50 $ 50.80 At standard, each set of covers should require 5.6 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. (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.)
