Answer:
1. The standard quantity 2318kg
2. The standard materials cost allowed $ 16226
3.Materials Spending Variance= 327 Unfavorable
4. The materials price variance 327 Unfavorable
5. The materials quantity variance 1330 Unfavorable
Explanation:
1. The standard quantity of kilograms of plastic (SQ) that is allowed to make 3,800 helmets= 3800* 0.61= 2318kg
2. The standard materials cost allowed (SQ × SP) to make 3,800 helmets= 3800*0.61*7= $ 16226
3. The materials spending variance= Purchase Price Variance= Actual Price *Actual Quantity - Standard Price * Actual Quantity
Materials Spending Variance= $16,553- $ 16226
Materials Spending Variance= 327 Unfavorable
4. The materials price variance = (Actual Price * Actual Quantity)- (Standard Price * Actual Quantity)
= $16,553- $ 16226= 327 Unfavorable
5. The materials quantity variance= (Standard Price * Actual Quantity)-(Standard Price * Standard Quantity)
=( 7* 2,508)- (7*2318kg)= 17556-16226= 1330 Unfavorable
