The predetermined manufacturing overhead rate is $14.00 per direct labor hour ($21.00 = 1.5). It was computed from a master manufacturing overhead budget based on normal production of 7,650 direct labor hours (5,100 units) for the month. The master budget showed total variable costs of $49,725 ($6.50 per hour) and total fixed overhead costs of $57,375 ($7.50 per hour). Actual costs for October in producing 3,300 units were as follows. Direct materials (3,430 pounds) Direct labor (4,830 hours) Variable overhead Fixed overhead Total manufacturing costs $ 21,266 56,511 49,894 21,706 $149,377 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. (a) Compute all of the materials and labor variances.
