Answer:
FIFO - $1350
LIFO - $900
Explanation:
Total inventory = 250 + 350 + 450 = 1050
Total inventory sold = 1050 - 150 = 900
FIFO means first in , first out. It means that it is the first purchased inventory that is the first to be sold. So the ending inventory would consist of the last purchased inventory. So the cost of the ending inventory would be allocated to the 3rd purchase of inventory
150 x $9 = $1350
LIFO means last in first out. It means that it is the last purchased inventory that is the first to be sold. So the ending inventory would consist of the first purchased inventory. So the cost of the ending inventory would be allocated to the 1st purchase of inventory
150 x $6 = $900
