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	15	units at $27	$405
July 7	Purchase	8	units at $30	240
Nov. 23	Purchase	8	units at $31	248
		31	units	$893

There are 19 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	$
