Periodic Inventory Using FIFO, LIFO, and Weighted Average Cost Methods

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

Jan. 1	Inventory	7	units at $48	$336
Aug. 7	Purchase	16	units at $50	800
Dec. 11	Purchase	13	units at $51	663
		36	units	$1,799

There are 20 units of the item in the physical inventory at December 31. The periodic inventory system is used. Determine the inventory cost using (a) the first-in, first-out (FIFO) method; (b) the last-in, first-out (LIFO) method; and (c) the weighted average cost method (round per unit cost to two decimal places and your final answer to the nearest whole dollar).
