Assume that Chen uses the first-in, first-out method. Compute the cost of goods sold for 2012 and the ending inventory balance at December 31, 2012, for product A. b. Assume that Chen uses the last-in, first-out method. Compute the cost of goods sold for 2012 and the ending inventory balance at December 31, 2012, for product A. c. Assume that Chen uses the weighted average cost method. Compute the cost of goods sold for 2012 and the ending inventory balance at December 31, 2012, for product A.
