Final answer:
Using the LIFO inventory method, the value of the ending inventory on June 30 is -$482,000.
Step-by-step explanation:
The LIFO (Last In, First Out) inventory method assumes that the most recent inventory purchases are sold first. To calculate the value of the ending inventory on June 30 using the LIFO method, we start by calculating the cost of units sold. We subtract the cost of the units sold from the total cost of inventory purchases to obtain the value of the ending inventory.
Cost of units sold:
June 28 purchase: 150 units x $1,450 = $217,500
June 15 purchase: 150 units x $1,800 = $270,000
Total cost of units sold: $217,500 + $270,000 = $487,500
Value of ending inventory: Total cost of inventory purchases - Cost of units sold
$5,500 - $487,500 = $-482,000
