Rogen Corporation manufactures a single product. The standard cost per unit of product is shown below. Direct materials1 pound plastic at $6 per pound $ 6.00 Direct labor0.50 hours at $11.00 per hour 5.50 Variable manufacturing overhead 2.75 Fixed manufacturing overhead 2.25 Total standard cost per unit $16.50 The predetermined manufacturing overhead rate is $10 per direct labor hour ($5.00 0.50). It was computed from a master manufacturing overhead budget based on normal production of 2,500 direct labor hours (5,000 units) for the month. The master budget showed total variable costs of $13,750 ($5.50 per hour) and total fixed overhead costs of $11,250 ($4.50 per hour). Actual costs for October in producing 3,000 units were as follows. Direct materials (3,100 pounds) $ 18,910 Direct labor (1,400 hours) 15,680 Variable overhead 10,498 Fixed overhead 6,302 Total manufacturing costs $51,390 The purchasing department buys the quantities of raw materials that are expected to be used in production each month. Raw materials inventories, therefore, can be ignored.
