Answer:
FIFO
Weighted average
LIFO
Step-by-step explanation:
Beg inventory (400 units @ $28) $ 11,200
Purchases (475 units @ $35) $ 16,625
Goods available 875 units $ 27,825
W/A 27,825 / 875 = $31.8
LIFO will use first the newest units thus, the more expenses ($35) making a higher COGS
while FIFO will use first the oldest units thus, more cheap( $28) making lower COGS
W/A will fit between them
As FIFO makes COGS lower the income will be higher thus, taxes too.
W/A will follow as used 31.8 units
and then, LIFO with the higher COGS
