In its first month of operations, Cerretti Company made three purchases of merchandise in the following sequence: (1) 300 units at $45.67, (2) 400 units at $59.37, and (3) 500 units at $68.51. Compute the cost of the ending inventory under the average-cost method, assuming there are 300 units on hand. (Round average cost to 2 decimal places, e.g. 3.25. Use this rounded amount to calculate cost of ending inventory.)
