Compute ending inventory and cost of goods sold using moving- average cost, assuming the Company uses the perpetual inventory system

Answer 1

First of all format of data is confusing. I am assuming the Dec 5 and Dec 22 units are sold units and other are purchases.

Calculation of ending inventory and cost of goods sold using moving- average cost, assuming the Company uses the perpetual inventory system

Perpetual Moving Average	Goods Purchased			Cost of Goods Sold			Inventory Balance
	# of units	Unit Cost	Cost per unit	# of units	Cost per unit	Cost of goods sold	Total Cost of Goods (a)	Total Available Units (b)	Unit Average Cost (a/b)
Beginning Inventory							$1,800.00	3000	$0.6000
Purchases Dec.3	4000	$0.74	$2,960.00				$1,800.00	3000
							$2,960.00	4000
							$4,760.00	7000	$0.6800
Sales Dec.5				4400	$0.68	$2,992.00	$1,768.00	2600	$0.6800
Purchases Dec.17	2200	$0.80	$1,760.00				$1,768.00	2600
							$1,760.00	2200
							$3,528.00	4800	$0.7350
Sales Dec.22				2100	$0.7350	$1,543.50	$1,984.50	2700	$0.7350
TOTAL						$4,535.50

Cost of Goods Sold = $4,535.50

Ending Inventory = $1,984.50
