Answer and Explanation:
The computation of total, price, and quantity variances for materials and labor is shown below:-
Total materials variance = Total Materials cost as per standard – Total cost of materials actual
= (160 × 9 × $1.90) - $4,410
= $2,736 - 4410
= -$1,674 Unfavorable
Materials price variance = Actual quantity at Standard price - Actual quantity at Actual price
= (2100 pounds × $1.90) - (2100 × $4,100 ÷ 2,100)
= (2100 pounds × $1.90) - (2100 × $2.10)
= 3990 - 4410
= -$420 Unfavorable
Materials quantity variance = Standard quantity at Standard price - Actual quantity at Standard price
= (160 × 9 × $1.90) – (2100 × 1.90)
= -$1254 Unfavorable
Total Labor variance = Total Labor cost as per standard - Total cost of Labor actual
= (160 × 4 × $10) - $6,664
= $6,400 - $6,664
= -$264 Unfavorable
Labor price variance = Actual hours at Standard rate - Actual hours at Actual rate
= (680 × $10) - (680 × $9.80)
= $6,800 - $6,664
= $136 Favorable
Labor quantity variance = Standard hours at Standard rate - Actual hours at Standard rate
= (160 × 4 × $10) - (680 × $10)
= -$400 Unfavorable
