Solution:
Purchase price and usage variances for Aluminum:
Standard Price ofAluminum (SP) = $25
Actual Price of Aluminum (AP) = $28.50
Standard Quantity of Aluminum for 920 units (SQ) = 920* 4 pounds = 3680 pounds
Actual Quantity of aluminum consumed (AQ)= 3450 pounds
Actual quantity of Aluminum purchased = Quantity consumed + closing Inventory of aluminum - opening inventory of aluminum = 3450 +30-50 = 3430 pounds
Price Variance for Aluminum = (SP-AP)*Actual Quantity Purchased = ($25-$28.50)*3430 = $12,005 Unfavouable
Usage Variance For Aluminum = (SQ-AQ)*SP = (3680-3450)*25 = $5,750
