Answer:
a. both the cost of the goods sold and the cost of ending inventory.
Explanation:
The physical count is used in the periodic inventory system to calculate the amount of ending inventory. However the cost of goods sold can be derived from using the ending inventory count. Suppose we have ending inventory of 100 units and Purchases were 500 units Also there were no beginning inventory units so the Cost of goods Sold can be calculated as
Cost of Goods Sold= Beginning Inventory Add Purchases Less Ending Inventory
Cost of Goods Sold= 0 + 500- 100= 400
