Answer:
The amount of cost of goods sold for the month is $127,321.60.
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<em> Periodic Inventory System</em> 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
