Answer:
The difference is $612
Step-by-step explanation:
By using the Periodic inventory system Fulbright Corp. calculates its Cost of Sales and Inventory at the end of a certain period. In this case at year end.
FIFO
FIFO assumes that the units to arrive first will be sold first. Meaning inventory will be valued using recent prices.
FIFO inventory = 36 units x $122 = $4,392
LIFO
LIFO assumes that the units to arrive last will be sold first. Meaning that the inventory will be valued using earliest (old) prices.
LIFO inventory = 36 units x $139 = $5,004
Conclusion
Difference = LIFO inventory - FIFO inventory
= $5,004 - $4,392
= $612
