Answer:
$7,815
Step-by-step explanation:
As per Perpetual LIFO inventory valuation method the inventory purchased at last will be sold first and the value of ending inventory can be calculated as follows. The inventory sold has been deducted from the purchased inventory in that period first and then has been deducted from the previous period to arrive at the cost of ending inventory;
January: 8 units x $180 = $1,440
February: 20 units x $185 = $3,700
May: 11 units x $190 = $2,090
September: 3 units x $195 = $585
Cost of Ending Inventory of 42 units is $7,815
