Oriole Corporation manufactures a single product. The standard cost per unit of product is shown below. The predetermined manufacturing overhead rate is $14 per direct labor hour ($7.00+0.50). It was computed trom a master manufacturing overhead budget based on normal production of 2.500 direct labor hours ( 5,000 units) for the month. The master budget showed total variable costs of $16,250($6.50 per hour) and total foed overhead costs of $18,750 (\$7.50 per hour). Actual costs for October in producing 4,400 units were as follows. (b) Compute the total overhead variance. Oriole Corporation manufactures a single product. The standard cost per unit of product is shown below.
