Answer and Explanation:
The computation is shown below:
a. The labor rate variance is
= actual labor cost - (standard rate × actual hours)
= ($131,340) - ($12.75 × 6,600 hours)
= $47,190 unfavorable
b. The labor efficency variance is
= (actual hours - standard hours) × standard rate
= (6,600 - (1,600 × 16) × $12.75
= $242,250 favorable
In this way it can be calculated and the same is to be considered and relevant
