Answer:
Instructions are listed below
Explanation:
Giving the following information:
Beginning inventory 2,830 units at $8
Purchases 8,110 units at $10
Sales 9,418 units at $13
Average cost= (8 + 10)/2=9
FIFO (first-in, first-out)
COGS= 2,830*8 + 6,588*10= $88,520
LIFO (last-in, first-out)
COGS= 8,110*10 + 1,308*8= $91,564
Average cost method:
COGS= 9,418*9= $84,762
