Answer: See explanation
Step-by-step explanation:
a. Compute the predetermined overhead allocation rate for each activity.
Predetermined overhead rate = Budgeted cost/Allocation base unit
Materials handling: $12,000/4000 = $3
Machine setup: $3100/10 = $310
Insertion of parts: $42000/4000 = 10.5
Finishing: $86000/1000 = 86
b. Compute the expected indirect manufacturing cost of each bumper.
= Total budgeted overhead cost/Expected total production
= $143100/500
= $282.6 per bumper.
