Explanation / Answer

a).

Total Overhead = $262000 + $128000 = $390000

Total Machine Hours = 4*3000 + 2*5000 + 3*6000 = 12000 + 10000 + 18000 = 40000

Overhead Rate per Machine Hour = $390000/40000 = 9.75 per hour

Product Cost Per unit :-

b) Overhead Rate :-

Department A = $262000 / (12000+15000) = 9.7 per direct labor hour

Department B = $128000 / 18000 = 7.11 per machine hour
