Answer:
1. 1,922
2. $13,454
3. $254 Unfavorable
4. 831 Favorable
$1,085 Unfavorable
Step-by-step explanation:
1. The computation of standard quantity of kilograms of plastic is shown below:-
Standard quantity of kilograms allowed = Helmets manufactured × Required kilograms of plastic
= 3,100 × 0.62
= 1,922
2. The computation of standard materials cost allowed is shown below:-
Standard cost allowed for actual output = Standard quantity of kilograms allowed × Cost per kilogram
= 1,922 × $7
= $13,454
3. The computation of materials spending variance is shown below:-
Materials spending variance = Plastic cost - Standard cost allowed for actual output
= $13,708 - $13,454
= $254 Unfavorable
4. The computation of materials price variance and the materials quantity variance is shown below:-
Materials price variance = Plastic cost - (Plastic in kilograms × Cost per kilograms)
= $13,708 - (2,077 × $7)
= 831 Favorable
Materials quantity variance = Cost per kilograms × (Plastic in kilograms - Standard quantity of kilograms allowed)
= $7 × (2,077 - 1,922)
= $1,085 Unfavorable
So, we have applied the above formulas.
