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

Direct materials1 pound plastic at $6.00 per pound		$ 6.00
Direct labor2.0 hours at $11.85 per hour		23.70
Variable manufacturing overhead		12.00
Fixed manufacturing overhead		12.00
Total standard cost per unit		$53.70

The predetermined manufacturing overhead rate is $12.00 per direct labor hour ($24.00 2.0). It was computed from a master manufacturing overhead budget based on normal production of 11,800 direct labor hours (5,900 units) for the month. The master budget showed total variable costs of $70,800 ($6.00 per hour) and total fixed overhead costs of $70,800 ($6.00 per hour).
