Costello Corporation manufactures a single product. The standard cost per unit of product is shown below.
| Direct materials 2 pound plastic at $6.52 per pound | $ 13.04 | |
| Direct labor 2.50 hours at $12.00 per hour | 30.00 | |
| Variable manufacturing overhead | 20.00 | |
| Fixed manufacturing overhead | 20.00 | |
| Total standard cost per unit | $83.04 |
The predetermined manufacturing overhead rate is $16 per direct labor hour ($40.00 2.50). It was computed from a master manufacturing overhead budget based on normal production of 15,000 direct labor hours (6,000 units) for the month. The master budget showed total variable costs of $120,000 ($8.00 per hour) and total fixed overhead costs of $120,000 ($8.00 per hour). Actual costs for October in producing 4,100 units were as follows.
| Direct materials (8,350 pounds) | $ 56,446 | |
| Direct labor (10,130 hours) | 125,004 | |
| Variable overhead | 121,194 | |
| Fixed overhead | 44,956 | |
| Total manufacturing costs | $347,600 |
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.
