Answer:
Actual quantity= 1,080 hours
Step-by-step explanation:
Giving the following information:
Predetermined overhead application rate= $5.00/hour.
They had 1000 standard hours
Unfavorable variable overhead efficiency variance= $400
To calculate the number of actual hours incurred, we need to use the following formula:
Variable overhead efficiency variance= (Standard Quantity - Actual Quantity)*Standard rate
-400 = (1,000 - AQ)*5
-400 - 5,000 = -5AQ
-5,400/5= -AQ
Actual quantity= 1,080 hours
