Sunland Corporation manufactures a single product. The standard cost per unit of product is shown below. The predetermined manufacturing overhead rate is $16 per direct labor hour ($32.002.0). It was computed from a master manufacturing overhead budget based on normal production of 12,000 direct labor hours (6,000 units) for the month. The master budget showed total variable overhead costs of $66,000 ( $5.50 per hour) and total fixed overhead costs of $126,000 ( $10.50 per hour). Actual costs for October in producing 4,800 units were as follows.
