Topic: Inventory Valuation Methods
Step 1: Understanding the Question:

Step 2: Detailed Explanation:
In retail, especially with perishable goods, it is logical to sell the items that arrived first.
FIFO (First-In, First-Out): Assumes the first items put in inventory are the first ones sold.
LIFO (Last-In, First-Out): Assumes the most recent items are sold first (common in non-perishables like coal or stone).
AVG: Uses a weighted average of costs.
Step 3: Final Answer:
The method that assumes earliest goods are sold first is FIFO.
