Answer:
Shellhammer Company
Ending inventory = $712
Cost of goods sold = $2,492
Explanation:
a) Data and Calculations:
Date Item Units Unit Cost Total Cost
September 1 Inventory 100 $3.34 $334.00
September 8 Purchases 450 3.50 1,575.00
September 18 Purchases 350 3.70 1,295.00
September 30 Total 900 $3,204.00
Ending inventory 200
Cost of goods sold 700
Weighted Average cost = Total cost of goods available for sale/Total units available for sale
= $3,204/900 = $3.56
Value of Ending Inventory = $3.56 * 200 = $712
Value of Cost of goods sold = $3.56 * 700 = $2,492
b) The weighted average inventory costing, under the period inventory system, used by Shellhammer is an assumption that the costs attributable to ending inventory and cost of goods sold are determined from the average cost per unit and that these the average cost is ascertained at the end of the period. Therefore, the cost of beginning inventory and purchases are accumulated and divided by the units of goods available for sale.
