Answer:
The ending inventory for the month of May using the LIFO inventory cost method is $324.
Explanation:
LIFO
LIFO method assumes that the last goods purchased are the first ones to be issued to the final customer.
This means valuation of inventory will use the value of the earliest goods purchased.
Ending Inventory : 2 units × $14 = $28
5 units × $16 = $80
12 units × $18 = $216
Total = $324
Conclusion :
The ending inventory for the month of May using the LIFO inventory cost method is $324.
