Periodic Inventory Using FIFO, LIFO, and Weighted Average Cost Method.

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

Jan. 1	Inventory	10	units at $35	$350
Aug. 13	Purchase	18	units at $36	648
Nov. 30	Purchase	13	units at $38	494
Available for sale		41	units	$1,492

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).

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