Saved ing Enabled: Module 4 Exam (Chapters 8 - 10) i Kropf Inc. has provided the following data concerning one of the products in its standard cost system. Variable manufacturing 8 overhead is applied to products on the basis of direct labor-hours. Standard Quantity or Standard Price or Rate Inputs Hours per Unit of Output Direct materials 8. 80 liters $ 8.40 per liter Direct labor 0. 46 hours $28 . 70 per hour Variable manufacturing overhead 9. 40 hours $ 7.30 per hour 1:52:32 The company has reported the following actual results for the product for September: Actual output 11, 060 units Raw materials purchased 98,400 liters Actual cost of raw materials purchased $854, 500 Raw materials used in production 96, 830 liters Actual direct labor-hours 4,000 hours Actual direct labor cost $120, 302 Actual variable overhead cost $ 25,414 Required: a. Compute the materials price variance for September. b. Compute the materials quantity variance for September. c. Compute the labor rate variance for September. d. Compute the labor efficiency variance for September. e. Compute the variable overhead rate variance for September. f. Compute the variable overhead efficiency variance for September. (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.) a. Materials price variance b. Materials quantity variance C. Labor rate variance d. Labor efficiency variance Variable overhead rate variance Variable overhead efficiency variance Graw
