AAA Hardware uses the LIFO method to report its inventory. Inventory at the beginning of the year consisted of 10,000 units of the company's one product. These units cost $15 each. During the year, 60,000 units were purchased at a cost of $18 each and 64,000 units were sold. Near the end of the fiscal year, management is considering the purchase of an additional 5,000 units at $18. What would be the effect of this purchase on income before income taxes? Would your answer be the same if the company used FIFO instead of LIFO
