Answer:
A. FIFO
Cost of the ending inventory $12,150
Cost of goods sold $52,200
B. LIFO
Cost of the ending inventory $10,800
Cost of goods sold $53,550
C. AVERAGE COST
Cost of the ending inventory $11,700
Cost of goods sold $52,650
Explanation:
A. Computation for the cost of the ending inventory and the cost of goods sold under FIFO
Cost of the ending inventory = 90 units*($44,550/330 units)
Cost of the ending inventory=90 units**135
Cost of the ending inventory=$12,150
Cost of goods sold =($44,550+$19,800)-$12,150
Cost of goods sold =$64,350-$12,150
Cost of goods sold =$52,200
2.Computation for the cost of the ending inventory and the cost of goods sold under LIFO
Cost of the ending inventory = 90 units*($19,800/165)
Cost of the ending inventory =90 units*$120
Cost of the ending inventory = $10,800
Cost of goods sold =($44,550+$19,800)-$10,800
Cost of goods sold =$64,350-$10,800
Cost of goods sold =$53,550
3.Computation for the cost of the ending inventory and the cost of goods sold under Average-cost
Cost of the ending inventory = 90 units*($44,550+$19,800)/(330 units+165 units)
Cost of the ending inventory = 90 units*($64,350/495 units)
Cost of the ending inventory = 90 units*$130
Cost of the ending inventory = $11,700
Cost of goods sold =($44,550+$19,800)-$11,700
Cost of goods sold =$64,350-$11,700
Cost of goods sold =$52,650
