Answer:
$15,200 favorable
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 3,800 hours
And, the standard direct labor hours equal to
= 800 units × 3.5
= 2,800 hours
Standard variable overhead rate $ 15.20 per hour
Now put these values to the above formula
So, the value would equal to
= (3,800 hours - 2,800 hours) × $15.20
= $15,200 favorable
