Problem 9. Variance Analysis Bronfenbrenner Co. uses a standard cost system for its single product in which variable overhead is applied on the basis of direct labor hours. The following information is given: Standard costs per unit: Raw materials (1.5 grams x S16 per gram) Direct labor (0.75 hours x S8 per hour) S6.00 Variable overhead (0.75 hours $3 per $24.00 S2.25 hour) Actual experience for current year Units produced Purchases of raw materials (21,000 grams x S17 per gram) 22 ,400 units $357,000 33,400 grams Raw materials used Direct labor (16,750 hours x $8 per hour) Varia Required Compute the following variances for raw materials, direct labor, and variable overhead, assuming that the price variance for materials is recognized at point of purchase: a. Direct materials price variance. $134,000 ble overhead cost incurred S48,575 b. Direct materials quantity variance. c. Labor rate variance d. Labor efficiency variance. e. Variable overhead rate variance. f. Variable overheadefficiency variance
