Periodic inventory by three methods; cost of goods sold

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

Jan. 1	Inventory	50 units at $102
Mar. 10	Purchase	70 units at $112
Aug. 30	Purchase	20 units at $118
Dec. 12	Purchase	60 units at $120

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

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