The amount of the cost of goods sold, using the perpetual inventory system, is <u>$120</u>.
<h3>What is the perpetual inventory system?</h3>
The perpetual inventory system is an inventory management system that records all inventory transactions as they occur and not at the end of the accounting period when inventory counts are carried out.
It is the opposite of the periodic inventory system. Using the perpetual inventory system, entries are made directly to the inventory account and the cost of goods sold with each inventory transaction.
<h3>Data and Calculations:</h3>
Beginning inventory 3 units at $20 = $60
April 10 Purchase 5 units at $20 = $100
Total cost of goods available for sale = $160
April 12 Sales 6 units
Ending inventory = 2 (8 - 6) = $40
Cost of goods sold = $120 ($20 x 6) or ($160 - $40)
Thus, the amount of the cost of goods sold, using the perpetual inventory system, is <u>$120</u>.
