CP7-1 (Algo) Analyzing the Effects of Four Alternative Inventory Costing Methods [LO 7-3] Scrappers Supplies tracks the number of units purchased and sold throughout each accounting period but applies its inventory costing method at the end of each period, as if it uses a periodic inventory system. Assume its accounting records provided the following information at the end of the annual accounting period, December 31. TIP: Although the purchases and sales are listed in chronological order, Scrappers determines the cost of goods sold after all of the purchases have occurred. Required: 1.

Last-in, first-out. b. Weighted average cost. c. First-in, first-out. d. Specific identification, assuming that the April 1 sale was selected one-fifth from the beginning inventory and four-fifths from the purchase of March 2. Assume that the sale of August 1 was selected from the purchase of June 30. 2. Of the four methods, which will result in the highest gross profit? Which will result in the lowest income taxes?
