Answer:
The amount of cost of goods sold for the month is $127,321.60.
Step-by-step explanation:
The Weighted Average Cost Method uses a Unit Cost calculated on the Average to value the Cost of Goods Sold and Ending Inventory.
Since the Periodic Inventory System is being used, the Unit Cost will be calculated on Goods Available for Sale.
Average Unit Cost = Total Cost of Goods Available for Sale ÷ Units Available for Sale.
Total Cost of Goods Available for Sale = 7,300 × $9.00 + 3,100 × $10.00 + 12,200 × $10.50 = $224,800
Units Available for Sale = 7,300 + 3,100 + 12,200 = 22,600
Therefore,
Average Unit Cost = $224,800 ÷ 22,600 = $9.947
Cost of Goods Sold = Units Sold × Units Available for Sale
= 12,800 × $9.947
= $127,321.60
