Quizplus · Accepted Answer

Machining Department overhead cost = Fixed manufacturing overhead cost + (Variable overhead cost per machine-hour × Total machine-hours in the department)
= $136,800 + ($1.80 per machine-hour × 19,000 machine-hours)
= $136,800 +$34,200 = $171,000
Predetermined overhead rate = Estimated total manufacturing overhead cost ÷ Estimated total amount of the allocation base incurred = $171,000 ÷ 19,000 machine-hours = $9.00 per machine-hour
