Answer:
$11.165 unfavorable
Step-by-step explanation:
The formula to compute the variable overhead efficiency variance is shown below:
= (Actual direct labor hours - standard direct labor hours) × variable overhead per hour
where,
Actual direct labor hours is 2,975
And, the standard direct labor hours equal to
= 250 units × 9
= 2,250
Now put these values to the above formula
So, the value would equal to
= (2,975 - 2,250) × $15.40
= $11.165 unfavorable
