Crane Corporation manufactures a single product. The standard cost per unit of product is shown below. $ 8.00 17.55 Direct materials-1 pound plastic at $8.00 per pound Direct labor - 1.50 hours at $11.70 per hour Variable manufacturing overhead Fixed manufacturing overhead Total standard cost per unit 9.75 5.25 $40,55 The predetermined manufacturing overhead rate is $10 per direct labor hour ($15.00 +1.50). It was computed from a master manufacturing overhead budget based on normal production of 8,100 direct labor hours (5,400 units) for the month. The master budget showed total variable costs of $52,650 (56,50 per hour) and total fixed overhead costs of $28,350 ($3.50 per hour). Actual costs for October in producing 3.200 units were as follows. $ 27,378 Direct materials (3,380 pounds) Direct labor (4.700 hours) 55,930 Variable overhead 35.518 Sant Per The predetermined manufacturing overhead rate is $10 per direct labor hour ($15.00 + 150 it was computed from a master manufacturing overhead budget based on normal production of 8.100 direct labor hours (S.400 units for the month The master budget showed total variable costs of $52.650 ($6,50 per hour and total foued overhead costs of $28.350 ($350 per hour.
