Problem 11-1A Your answer is partially correct. Try again. Rogen Corporation manufactures a single product. The standard cost per unit of product is shown below Direct materials-1 pound plastic at $7 per pound Direct labor-1.6 hours at $12 per hour Variable manufacturing overhead Fixed manufacturing overhead Total standard cost per unit $ 7 19.2 12 $42.2 The predetermined manufacturing overhead rate is $10 per direct labor hour ($16+1.6). It was computed from a master ma00 ($2.5 per hour), Actual costs for Oct labor hours (5.,000 units) for the month. The master budget showed total variable costs of s manufacturing overhead budget based on normal production of 8,000 d $60,000 ($7.5 per hour) and total fixed overhead costs of $20,000 ($2.5 per hour) Direct materials (5,100 pounds) Direct labor (7,400 hours) Variable overhead Fixed overhead 36,720 92,500 59,700 21,000 $209,920 Total manufacturing costs The purchasing department buys the quantities of raw materials that are expected to be used in production each month, Raw materials inventories, t herefore, can be ignored. Compute all of the materials and labor variances. (Round answers to o decimal places, e.g. 125.) Total materials variance Materials price variance Unfavorabie
