Assume a firm starts off the period with 10 units, each with a value of $5. Then the firm buys 10 units at a cost of $7 and 8 more units at a cost of $10. After these purchases, the firm sells 20 units at a selling price of $15 per unit. Assuming that the firm uses the LIFO inventory costing method, what is the value of the ending inventory that the firm will report on the balance sheet after the sale of these 20 units?
