Answer:
FIFO
Cost of Goods Sold = $17640
Inventory = $12960
LIFO
Cost of Goods Sold = $19160
Inventory = $11440
Weighted Average
Cost of Goods Sold = $18360
Inventory = $12240
Explanation:
FIFO
FIFO stands for First In First Out, meaning that Inventory bought in first should be the first to be sold
Cost of Goods Sold = (100×60)+(150×68)+(20×72)
Inventory = 180 ×72
LIFO
LIFO stands for Last In First Out, meaning that the recent inventory is sold first
Cost of Goods Sold = (200×72)+(70×68)
Inventory = (80×68)+(100×60)
Weighted Average
A new unit cost of inventory is calculated on each purchase using the average
Cost of Goods Sold = (270×68)
Inventory = (180×68)
