Rogen Corporation manufactures a single product. The standard cost per unit of product is shown below.

Direct materials1 pound plastic at $7.00 per pound		$ 7.00
Direct labor2.5 hours at $11.80 per hour		29.50
Variable manufacturing overhead		17.50
Fixed manufacturing overhead		17.50
Total standard cost per unit		$71.50

The predetermined manufacturing overhead rate is $14.00 per direct labor hour ($35.00 2.5). It was computed from a master manufacturing overhead budget based on normal production of 13,250 direct labor hours (5,300 units) for the month. The master budget showed total variable costs of $92,750 ($7.00 per hour) and total fixed overhead costs of $92,750 ($7.00 per hour). Actual costs for October in producing 3,900 units were as follows.

Direct materials (4,030 pounds)		$ 28,613
Direct labor (9,600 hours)		116,160
Variable overhead		103,738
Fixed overhead		34,862
Total manufacturing costs		$283,373

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.
