Answer:
Since the information is missing, I searched for a similar question and found the attached image. The numbers vary slightly, but you can use this exercise as an example:
cost assigned to ending inventory under:
FIFO = $108,530 - $85,045 = $23,485
LIFO = $108,530 - $85,430 = $23,100
weighted average = $108,530 - $85,697 = $22,833
specific identification = $108,530 - $85,245 = $23,285
first we should calculate COGS:
under FIFO
March 15 sales = (660 x $60) + (55 x $57) = $42,735
September 10 sales = (275 x $57) + (110 x $45) + (160 x $65) + (185 x $61) = $42,310
total = $85,045
under LIFO
March 15 sales = (110 x $45) + (330 x $57) + (275 x $60) = $40,260
September 10 sales = (570 x $61) + (160 x $65) = $45,170
total = $85,430
under weighted average
March 15 sales = 715 x ($108,530 / 1,830) = $42,404
September 10 sales = 730 x ( / 1,830) = $43,293
total = $85,697
under specific identification
For specific identification, units sold consist of 660 units from beginning inventory, 230 from the February 10 purchase, 110 from the March 13 purchase, 110 from the August 21 purchase, and 335 from the September 5 purchase.
(660 x $60) + (230 x $57) + (110 x $45) + (110 x $65) + (335 x $61) = $85,245
