Problem 16-75 (Algo) Comprehensive Variance Problem (LO 16-5, 6) Robinwood Fixtures manufactures two products, K4 and X7. The company prepares its master budget on the basis of standard costs. The following data are for September: Standards Direct materials Direct labor Variable overhead (per direct labor-hour) Fixed overhead (per month) Expected activity (direct labor-hours) $ 414,720 Actual results Direct material (purchased and used) Direct labor Variable overhead Fixed overhead Units produced (actual) K4 0.75 pounds at $6.60 per pound 1.25 hours at $24.60 per hour $ 19.80 17,280 9,600 pounds at $6.00 per pound 14,730 hours at $24.90 per hour $ 303,060 $ 379,740 12,060 units X7 1 pound at $7.20 per pound 1.50 hours at $30 per hour $ 21.60 $ 492,030 23,430 14,130 pounds at $7.50 per pound 22,230 hours at $31.20 per hour $ 457,212 $ 489,720 14,430 units Required: a. Prepare a variance analysis for each variable cost for each product. b. Prepare a fixed overhead variance analysis for each product. Note: For all requirements, Do not round intermediate calculations. Indicate the effect of each variance by selecting "F" for favorable, or "U" for unfavorable. If there is no effect, do not select either option.
