Answer:
a. 7400 U
b. 4120 U
Explanation:
A.Calculation to determine the labor rate variance for the month
Using this formula
Labor rate variance=(SR-AR) * AH
Let plug in the formula
Labor rate variance=[20.60-(153,180/7400)]*7400
Labor rate variance=(20.60-20.70)*7400
Labor rate variance=0.1*7400
Labor rate variance=7400 U
Therefore is Labor rate variance 7400 Unfavorable
b. Calculation to determine the labor efficiency variance for the month
Using this formula
Direct Labor Efficiency Variance = (Actual Direct Labor Hours Worked * Standard Labor Rate) - (Units Produced * Standard Direct Labor Hours per Unit * Standard Labor Rate)
Let plug in the formula
Direct Labor Efficiency Variance = (7400 hours x $20.60) - (1500 units x 4.8 hrs* $20.60)
Direct Labor Efficiency Variance = $152,440 - $148,320
Direct Labor Efficiency Variance = $4,120 UnFavorable
Therefore the labor efficiency variance for the month is $4,120 UnFavorable
