The total job cost for Job T498 is closest to:

A) $4,430
B) $3,670
C) $1,710
D) $3,480

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)= $497,000 + ($2.40 per direct labor-hour × 70,000 direct labor-hours)= $497,000 + $168,000 = $665,000
Predetermined overhead rate = Estimated total manufacturing overhead cost ÷ Estimated total amount of the allocation base = $665,000 ÷ 70,000 direct labor-hours = $9.50 per direct labor-hour
Overhead applied to a particular job = Predetermined overhead rate x Amount of the allocation base incurred by the job = $9.50 per direct labor-hour × 80 direct labor-hours = $760
