Answer:
Andover's variable-overhead efficiency variance is $-42,000 Unfavourable
Step-by-step explanation:
According to the given data we have the following:
Standard overhead rate=$ 5.60 per hour
Actual Hours=110,000 hours
Standard hours=47,000 units x 2.5 hours per unit
=117,500 hours
Therefore, in order to calculate the Andover's variable-overhead efficiency variance we would have to use the following formula:
Variable Overhead efficiency variance=Standard overhead rate x (Actual hours - standard hours)
=$ 5.60 x (110,000 - 117,500)
=$-42,000 Unfavourable
