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 980 hours each month to produce 1,960 sets of covers. The standard costs associated with this level of production are: Total Direct materials $ 32, 340 Direct labor $ 6,860 Variable manufacturing overhead (based on direct labor-hours) $ 1,960 Per Set of Covers $16.50 3.50 1.00 $21.00 During August, the factory worked only 1,000 direct labor-hours and produced 2,100 sets of covers. The following actual costs were recorded during the month: Direct materials (6,000 yards) Direct labor Variable manufacturing overhead Total $ 34,020 $ 7,770 $ 3,990 Per Set of Covers $16.20 3.70 1.90 $21.80 At standard, each set of covers should require 2.5 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 (ie, zero variance). Input all amounts as positive values.)
