Inits first month of operations, Blue Inc. made three purchases of inventory in the following sequence: (1) 370 units at $9 each, (2) 720 units at $13 each, and (3) 790 units at $12 each. A physical inventory count determined that there were 620 units on hand at the end of the month. Assuming Blue uses a periodic inventory system. Calculate the cost of the ending inventory and cost of goods sold using average. (Round final answers to 2 decimal places, eg. 1.25.) Weighted average cost $ Ending inventory $ Cost of goods sold
