E7-26.A Applying and Analyzing Inventory Costing Methods At the beginning of the current period, Chen carried 1,000 units of its product with a unit cost of $20. A summary of purchases during the current period follows: Unit Cost Units Cost Beginning Inventory Purchases: #1 #2. #3. 1,000 $20 22 $20,000 39,600 1,800 800 26 29 20,800 34,800 1,200 During the current period, Chen sold 2,800 units. Assume that Chen uses the first-in, first-out method. Compute its cost of goods sold for the current period and the ending inventory balance a. b. Assume that Chen uses the last-in, first-out method. Compute its cost of goods sold for the current period and the ending inventory balance. Assume that Chen uses the average cost method. Compute its cost of goods sold for the cur- rent period and the ending inventory balance. d.Which of these three inventory costing methods would you choose to: 1.
