The standard costs associated with this level of production are: Per Set Total of Covers Direct materials $38,640 $18.40 Direct labor $ 6,300 Variable manufacturing overhead (based on direct labor-hours) $ 3,150 1.50 $22.90 3.00 During August, the factory worked only 500 direct labor-hours and produced 2,000 sets of covers. The following actual costs were recorded during the month: Direct materials (5,000 yards) Direct labor Variable manufacturing overhead Per Set Total of Covers $36,000 $18.00 $ 6,400 3.20 54,400 2.20 $23.40 At standard, each set of covers should require 2.3 yords of material.
