Could you please help.thank-you

Answer 1

FIFO-first in, first out
300 @ 11.00
150 @ 10.50
200 @ 10.75
175 @ 10.00
100 @ 12.00
Beginning Inventory Total = 925
Ending Total = 300
Difference = sold = 625

FIFO-first in, first out
Items sold are assumed to be subtracted from the first ones purchased. Go down from the top and subtract from each purchase until you reach the number sold of 625.

300 @ 11.00--sold 300, 0 left
150 @ 10.50--sold 150, 0 left
200 @ 10.75--sold 175, 25 left
175 @ 10.00--sold 0, 175 left
100 @ 12.00--sold 0, 100 left

Calculate value of inventory remaining
25 @ 10.75 = $268.75
175 @ 10.00 = $1750.00
100 @ 12.00 = $1200.00
Total 300 units

268.75 + 1750.00 + 1200.00 = 3218.75

Value of 300 units on hand on Dec.31 = $3219.

Now, you do LIFO-last in, first out
Do the same as I did, except start subtracting from the last purchased until you reach the total sold (bottom to top).
