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 $3,800	$57,000
Aug. 7	Purchase	19	units at $3,900	74,100
Dec. 11	Purchase	15	units at $4,000	60,000
		49	units	$191,100

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).
