Step-by-step explanation:
Perpetual Inventory method calculates the Costs of Sales together with the Inventory value after each and every transaction.
Weighted Average Cost calculates a new unit cost after each and every Purchase made. This unit cost is then used to determine the Cost of Sales and Inventory Value.
New Unit Cost Calculations
Unit Cost = Total Available Cost ÷ Units Available for Sale
April 11
Unit Cost = (12 x $45 + 13 x $47) ÷ 25 = $46.04
April 21
Unit Cost = (7 x $46.04 + 9 x $60) ÷ 16 = $53.89
