FIFO

Explanation:

FIFO inventory system means the first purchased inventory are the first to be sold.

The LIFO inventory system means the last purchased inventory are the first to be sold.

The average cost inventory system means that the average cost of inventories are used as the cost of the goods sold.

For example, if a business has a beginning inventory of 5 biros at $2 each. On the first of December, the business purchased 10 pens at $2.50. On the 10th, 5 pens were purchased at $3. 15 pens are sold at $5 each. If the FIFO inventory system is used, the cost of goods sold would be = (5×$2)+(10×$2.50) = $35

Total revenue = $75

Net profit = $40.

If the LIFO inventory system is used, the cost of goods sold =(10 × $2.50) + (5×$3) = $40

Net profit = $35

The net profit is higher using the FIFO method.
