Answer:
FIFO
Explanation:
The FIFO inventory system assumes that it's the first purchased inventory that is sold. So in a period of falling prices, the FIFO inventory system results in reporting the highest cost of good sold.
For example, a business has inventory on the 1st of February that costs $30 for 10 goods, on the 10th, they purchased an extra 10 goods that costs $20. If 10 goods were sold, the FIFO inventory system would record the cost of goods sold as $30. If the LIFO inventory system is used, cost of goods sold would be $20. If the weighted average was used it would be $25.
