find the answer to the problem.

Periodic Inventory by Three Methods; Cost of Merchandise Sold

The units of an item available for sale during the year were as follows:

Jan. 1	Inventory	40 units @ $120
Mar. 10	Purchase	70 units @ $128
Aug. 30	Purchase	20 units @ $136
Dec. 12	Purchase	70 units @ $138

There are 80 units of the item in the physical inventory at December 31. The periodic inventory system is used.

Determine the inventory cost and the cost of merchandise sold by three methods. Round interim calculations to one decimal and final answers to the nearest whole dollar.
