Explanation:

The FIFO is a method used to account value for inventory. Under the method, the first item of inventory purchased is the first one sold.

1. Sep. 1,  Inventory 20 units, $20 per unit. Total $400

2. Sep. 4 Sold 10 units

Cost of goods sold = 10 x $20 = $200

The inventory = $400 - $200 = $200 (10 units, $20 per unit)

3. Sep. 10 Purchased 30 units, $25 per unit

The inventory: $950

10 units, $20 per unit, total $200

30 units $25 per unit, total $750

4.Sep. 17 Sold 20 units

Cost of goods sold = 10 x $20 + 10 x $25 = $200 + $250 = $450

The inventory: 20 units $25 per unit, total $500
