Answer:
B. $ 50 comma 400 unfavorable
Explanation:
The formula to compute the labor efficiency variance is shown below:
= Standard labor rate × (Standard hours for actual output - Actual hours)
where,
Standard labor rate is $28
Standard hours for actual output would be
= 1,600 cars × 3.25 direct labor hours per car
= 5,200 hours
And, the actual hour is 7,000 hours
Now put these values to the above formula
So, the value would equal to
= $28 × (5,200 hours - 7,000 hours)
= $50,400 unfavorable
