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 $114
Mar. 10	Purchase	60 units at $122
Aug. 30	Purchase	10 units at $126
Dec. 12	Purchase	80 units at $128

There are 60 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.
