Answer:
If the company uses FIFO, the gross profit will increase by $400.
Explanation:
Giving the following information:
purchases:
180 units of inventory for $7
280 units for $8
220 units for $9
Ending inventory= 260 units
First, we need to calculate the number of units sold:
Units sold= total units - ending inventory
Units sold= 680 - 260= 420 units
The difference between the gross profit under the two methods is the cost of goods sold. For LIFO we use the cost of the lasts units incorporated into inventory. For FIFO, the cost of the firsts units incorporated into inventory.
LIFO:
COGS= 220*9 + 200*8= $3,580
FIFO:
COGS= 180*7 + 240*8= $3,180
Difference= 3,580 - 3,180= $400
If the company uses FIFO, the gross profit will increase by $400.
