1. The cost of each product using a plant- wide rate based on machine hours :
Total budgeted machine hours = 160, 000 Total budgeted overhead dollar = $ 960, 000 Overhead rate = total budgeted overhead dollars / total budgeted machine hours $ 960, 000 / 160, 000 MH = $ 6. 00 per MH
43 X $ 6 per MH = $ 258 30 X $ 6 per MH = $ 180 25 X $ 6 per MH = $ 150 ITEM Direct material Direct labor Manufacturing overhead Total unit coast
