Quizplus · Accepted Answer

Estimated total manufacturing overhead cost = Estimated total fixed manufacturing overhead cost + (Estimated variable overhead cost per unit of the allocation base × Estimated total amount of the allocation base) = $237,000 + ($3.90 per machine-hour × 30,000 machine-hours) = $237,000 + $117,000 = $354,000
Predetermined overhead rate = Estimated total manufacturing overhead cost ÷ Estimated total amount of the allocation base = $354,000 ÷ 30,000 machine-hours = $11.80 per machine-hour
Overhead applied to a particular job = Predetermined overhead rate × Amount of the allocation base incurred by the job = $11.80 per machine-hour × 80 machine-hours = $944
