Final answer:
To calculate the amount of ending inventory using the LIFO method, subtract the cost of the units sold from the total cost of units purchased. In this case, the ending inventory on December 31 is $400.
Step-by-step explanation:
To calculate the amount of ending inventory on December 31 using the last-in, first-out (LIFO) method, we need to determine the cost of the units sold and subtract that from the total cost of units purchased.
First, calculate the cost of the units purchased in January:
200 units x $20 each = $4,000
Next, calculate the cost of the units purchased in February:
400 units x $40 each = $16,000
Since the company sold 460 units, the cost of the units sold will be the cost of the units purchased in February and 60 units from January.
The cost of the units sold will be:
460 units x $40 each + 60 units x $20 each = $18,400 + $1,200 = $19,600
To calculate the ending inventory, subtract the cost of the units sold from the total cost of units purchased:
Total cost of units purchased = $4,000 + $16,000 = $20,000
Ending inventory on December 31 = Total cost of units purchased - Cost of units sold = $20,000 - $19,600 = $400
