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)= $665,000 + ($3.00 per machine-hour × 70,000 machine-hours)= $665,000 + $210,000 = $875,000
Predetermined overhead rate = Estimated total manufacturing overhead cost ÷ Estimated total amount of the allocation base = $875,000 ÷ 70,000 machine-hours = $12.50 per machine-hour
Overhead applied to a particular job = Predetermined overhead rate x Amount of the allocation base incurred by the job = $12.50 per machine-hour × 90 machine-hours = $1,125 11ea7998_5f55_cd97_911b_7993c4f91074_TB2627_00_TB2627_00 11ea7998_5f55_cd98_911b_8103ee0194b4_TB2627_00_TB2627_00
