STEP-BY-STEP ANSWER:
Step 1: Identify the most recent inventory purchases, as these are assumed to be the first sold under LIFO.
Step 2: Calculate the cost of goods sold based on current inventory costs for the items sold.
Step 3: Remove the cost of the most recent items from the inventory records.
Step 4: Determine the remaining inventory value using the older cost layers.
Final Answer: LIFO assumes that the latest inventory additions are sold first, which typically results in a higher cost of goods sold during inflationary periods, leaving older costs in inventory.
