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

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

Aug. 13	Purchase	11	units at $35	385
Nov. 30	Purchase	10	units at $37	370
Available for sale		41	units	$1,395

There are 12 units of the item in the physical inventory at December 31. The periodic inventory system is used. Determine the inventory cost using the (a) first-in, first-out (FIFO) method; (b) last-in, first-out (LIFO) method; and (c) weighted average cost method (round per-unit cost to two decimal places and your final answer to the nearest whole dollar).

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