Answer: See explanation
Explanation:
The following can be derived from the question:
Actual quantity = 20,000 pounds
Actual price = $2.35
Standard price = $2.50 per unit
Actual hours = 750 hours.
The standard quantity will be calculated as:
= 4,000 units × 4.6
= 18,400 pounds
The Actual rate will be calculated as:
= Total labor cost / Actual hours
= $14,925 / 750
= $19.90
Standard hours will be:
= 0.2 hours × 4,000 units
= 800 hours.
Standard rate = $18 per hour
1. Compute the materials price and quantity variances for the month.
Material price variance:
= (AQ × AP) - (AQ × SP)
= (20,000 × $2.35) - (20,000 × $2.50)
= 47000 - 50000
= -3000
Material quantity variance:
= (AQ × SP) - (SQ × SP)
= (20,000 × $2.50) - (18,400 × $2.50)
= 50,000 - 46000
= 4000
2. Compute the labor rate and efficiency variances for the month.
Labor rate variance:
= (AH × AR) - (AH × SR)
= ($750 × $19.90) - (750 × $18)
= 14925 - 13500
= 1425
Labor efficiency variance:
= (AH × SR) - (SH × SR)
= (750 × $18) - (800 × $18)
= 13500 - 14400
= 900
