Answer:
Weighted average:
EI: 2,290
COGS: 9, 160
LIFO
EI: 2,400
COGS: 9,050
FIFO
EI: 3,000
COGS: 8,450
Explanation:
beginning 75 units at $ 18 = $ 1,350
Mar. 15 200 units at $21 = $ 4,200
Sept. 4 175 units at $24 = $ 1,800
July 20 125 units at $22 = $ 2,750
Dec. 2 50 units at $27 = $ 1,350
total units: 625 units cost of goods available: 11,450
average cost: 11,450/625 = $ 18.32 per unit
inventory units: 625 - 500 = 125 units
Weighted average:
EI: 125 x $18.32 = 2,290
COGS: 500 x $18.32 = 9, 160
500 units were sold
LIFO:
last units are sold while frist are inventory
ending inventory
beginning 75 units at $ 18 = $ 1,350
Mar. 15 50 units at $21 = $<u> 1,050 </u>
Total 2,400
COGS: available - ending inventory
11,450 - 2,400 = 9,050
FIFO
first units are sold while last are inventory
Dec. 2 50 units at $27 = $ 1,350
July 20 75 units at $22 = $ <u>1,650 </u>
Total 3,000
COGS: available - ending inventory
11,450 - 3,000 = 8,450
