Answer:
The correct answer is $936 favorable.
Step-by-step explanation:
According to the scenario, the computation of the given data are as follows:
we can calculate the variable overhead efficiency variance by using following formula:
Variable OH efficiency variance = (Actual Hours - Standard Hours) × Standard Rate
Where,
Standard hours = 4,600 × 0.60 = 2,760
By putting the data, we get
Variable OH efficiency variance = ( 2,500 - 2,760) × $3.60
= -$936 ( negative sign shows favorable)
= $936 Favorable
