Assume 900 units are on hand at the end of the month. Calculate the cost of goods available for sale, cost of goods sold, and ending inventory under the (a) FIFO, (b) LIFO, and (c) weighted average cost flow assumptions. Assume perpetual inventory system and sold 600 units between January 9 and January 28. (Round your intermediate calculations to 2 decimal places.)
