Answer:
D. $96,000
Explanation:
We will allocate the cost on maintenance by first stablishing a rate per maintenence hour:
As this is direct method we aren''t doing an allocation to other service department we directly allocate against production department A and B
total hours: 480 + 320 = 800
160,000 total cost /800 hours = 200 per hour
Department B hours: 480
allocate to department B: 480 x 200 = 96,000
