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	40 units at $120
Mar. 10	Purchase	60 units at $128
Aug. 30	Purchase	30 units at $134
Dec. 12	Purchase	70 units at $136

There are 60 units of the item in the physical inventory on December 31. The periodic inventory system is used.
