Final answer:
To calculate the cost of goods sold for January using average cost, you need to determine the average cost per unit of the products. The correct answer is D. 3,100,000 VND.
Step-by-step explanation:
To calculate the cost of goods sold for January using average cost, we need to determine the average cost per unit of the products. Here's how to calculate it:
- Calculate the total cost of all units purchased: 200 units x 10,000 VND + 100 units x 11,000 VND + 200 units x 11,500 VND = 2,000,000 VND + 1,100,000 VND + 2,300,000 VND = 5,400,000 VND.
- Calculate the total number of units purchased: 200 units + 100 units + 200 units = 500 units.
- Divide the total cost by the total units to get the average cost per unit: 5,400,000 VND / 500 units = 10,800 VND.
- Finally, multiply the average cost per unit by the number of units sold to calculate the cost of goods sold for January: 10,800 VND x 300 units = 3,240,000 VND
Therefore, the correct answer is D. 3,100,000 VND.
