P24.1A (LO 2, 3), AP Rogen Corporation manufactures a single product. The standard cost per unit of product is shown below. Direct materials--1 pound plastic at $7.00 per pound Direct labor-1.6 hours at $12.00 per hour Variable manufacturing overhead Fixed manufacturing overhead Total standard cost per unit $ 7.00 19.20 12.00 4.00 $42.20 The predetermined manufacturing overhead rate is $10 per direct labor hour ($16.00 + 1.6). It was com- puted from a master manufacturing overhead budget based on normal production of 8,000 direct labor hours (5,000 units) for the month. The master budget showed total variable costs of $60,000 ($7.50 per hour) and total fixed overhead costs of $20,000 ($2.50 per hour). Actual costs for October in producing 4,800 units were as follows. Direct materials (5,100 pounds) $ 36,720 Direct labor (7,400 hours) 92,500 Variable overhead 59,700 Fixed overhead 21,000 Total manufacturing costs $209,920 ne purchasing department buys the quantities of raw materials that are expected to be used in produc- on each month.
