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	14	units at $4,800	$67,200
Aug. 7	Purchase	17	units at $5,100	86,700
Dec. 11	Purchase	12	units at $5,200	62,400
	43	units	$216,300

There are 18 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)	$fill in the blank 1
b.	Last-in, first-out (LIFO)	$fill in the blank 2
c.	Weighted average cost
