Answer and Explanation:
a. The computation of the material price variance is shown below:
= Actual Quantity × (Standard Price - Actual Price)
= $7,260 × (2,200 pounds × $3.10 per pound)
= $440 unfavorable
b. The computation of the material quantity variance is shown below:
= Standard Price × (Standard Quantity - Actual Quantity)
= $3.10 × (2,200 pounds - (190 units × 6 pounds))
= $3,286 unfavorable
c. Total material variance
= Material price variance + material quantity variance
= $440 unfavorable + $3,286 unfavorable
= $3,726 unfavorable
d. The computation of the labor price variance is shown below:
= Actual Hours × (Actual price - Standard Price)
= $7,623 - (770 hours × $10)
= $77 favorable
e. The computation of the labor quantity variance is shown below:
= Standard Rate × (Actual Hours - Standard hours allowed for actual units)
= $10 × (770 hours - (190 units × 4 hours)
= $100 unfavorable
Total labor variance
= Labor rate variance + labor quantity variance
= $77 favorable + 100 unfavorable
= $23 unfavorable
