Answer:
d. $1,540 F
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 2,380
And, the standard direct labor hours equal to
= 5,200 units × 0.5
= 2,600 hours
Now put these values to the above formula
So, the value would equal to
= (2,380 hours - 2,600 hours) × $7
= 1,540 favorable
