The predetermined manufacturing overhead rate is $10 per direct labor hour ($15.00 ÷ 1.5). It was computed from a master manufacturing overhead budget based on normal production of 7,500 direct labor hours (5,000 units) for the month. The master budget showed total variable costs of $56,250 ($7.50 per hour) and total fixed overhead costs of $18,750 ($2.50 per hour). Actual costs for October in producing 4,900 units were as follows.

Direct materials (5,100 pounds) $ 37,230
Direct labor (7,000 hours) 87,500
Variable overhead 56,170
Fixed overhead
19,680

Total manufacturing costs
$200,580

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.
