Answer:
Predetermined overhead rate for department A = 1.4
Predetermined overhead rate for department B = $4
Step-by-step explanation:
The computation of predetermined overhead rates would be used in Dept A and Dept B, is shown below:-
The predetermined overhead rate for department A = Manufacturing overhead ÷ Machine hours
= $91,000 ÷ $65,000
= 1.4
The predetermined overhead rate for department B = Manufacturing overhead ÷ Machine hours
= $48,000 ÷ 12,000 hours
= $4
So, we have applied the above formula.
