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	4	units at $31	$124
Aug. 7	Purchase	20	units at $33	660
Dec. 11	Purchase	13	units at $35	455
		37	units	$1,239

There are 17 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).

a.	First-in, first-out (FIFO)	$
b.	Last-in, first-out (LIFO)	$
c.	Weighted average cost	$
