Instructions

Determine both Ending Inventory (EI) and Cost of Goods Sold (COGS) under each of the following methods and then calculate gross profit under each, assuming that the selling price per unit was $25 for all units sold.

Method	EI	COGS	Gross Profit
FIFO, periodic	10,800 + 16,000 = 26,800	67600 - 26,800 = 40,800	65,000 - 40,800 = 24,200
FIFO, perpetual	26,800	40,800	24,200
LIFO, periodic	5,600 + 16,000 = 21,600	35,200 + 10,800 = 46,000	65,000 - 46,000 = 19,000
LIFO, perpetual	???(enter formula, not just answers)	???	???
Weighted-average	16.90 * 1,400 = 23,660	16.90 * 2,600 = 43,940	65,000 - 43,940 = 21,060
Moving- average	???? (enter formula, not just answers)	????	????

Weighted-average cost per unit = 67,600/4,000 = $16.90

Sales Revenue = 2,600 units sold * 25 = 65,000

Sales revenue - COGS = Gross Profit
