Answer:
$9,800
Step-by-step explanation:
As for the information provided,
Under FIFO method the goods which are bought first are sold first.
Therefore, goods sold on 25 Feb will be from beginning inventory.
Thus, balance from beginning inventory after such sale = 500 - 300 units = 200 units @ $10
May 21 purchase 400 units @ $12
Jul 15 purchase 500 units @ $15
Therefore sale of 800 units on 10 December will be as follows:
200 units @ $10 = $2,000
400 units @ $12 = $4,800
200 units @ $15 = $3,000
Total cost of goods sold = $9,800
