Net sales units=Sales- Sales Returns

=105-12=93 units

Net Purchases units=135+(52-8)+25=204 units

No of units available for sale=opening inventory + Net Purchaes

=38+204=242 units

Cost of Goods available for sale=Cost of opening Inventory + Cost of Net purchase

Cost of opening Inventory=$1,444

Cost of Net purchases=135 x 42 +(52-8) x 44+25 x 48

=5,670+ 1,936+1,200

=$8,806

Cost of Goods available for sale=$1,444+$8,806

=$10,250

Cost Per unit= Cost of Goods available for sale/ No of units available for sale

=$10,250/242

=42.35

Calculate ending inventory, cost of goods sold, gross profit under each of the following methods. (1) LIFO. (2) FIFO. (3) Average-cost.(Round average-cost method answers to 2 decimal places, e.g. 1,250.25 and other answers to 0 decimal places, e.g. 1,250. Use weighted-average unit cost rounded to 2 decimal places for computations.)
