Answer:
D. $590
Step-by-step explanation:
Predetermined overhead rate = $15 per labour hour
Direct Material cost = $50
Labor rate = $75 per hour
Number of Direct labor hour = 6
Direct labor cost = 6 x 75 = $450
Overhead applied cost = Predetermined overhead rate x Direct labor hours
Overhead applied cost = 15 x 6 = $90
Total cost = $50 + $450 + $90
Total cost = $590
So, the correct answer is D. $590
