Answer:
E. $25,000 unfavorable
Step-by-step explanation:
The labor efficiency variance shall be calculated using the following formulas:
Labor efficiency variance=((Standard labor hours used to make the actual production )- (Actual labor hours used to make the actual production))* standard rate per hour
Standard labor hours used to make the actual production=15,000
Actual labor hours used to make the actual production=17,500
standard rate per hour=$10 per hour
Labour efficiency variance=(15,000-17,500)*10
=25,000 unfavourable
So based on the above discussion, the answer shall be E. $25,000 unfavorable
