Answer:
d) 34.17
Explanation:
we must first calculate the total overhead expenses = $120,000 (ordering and receiving) + $297,000 (machine setup) + $1,500,000 (machining) + $1,200,000 (assembly parts) + $300,000 (inspection) = $3,417,000
since overhead is applied based on direct labor hours, then the predetermined overhead rate = total overhead expenses / total direct labor hours = $3,417,000 / 100,000 labor hours = $34.17 per labor hour
