Human: Kohen has a business selling apples. Once a week, he orders 10 boxes of apples to add to his stock. If each box has 300 apples and he sells 3/4 of his stock in a certain week, what total number of apples is not sold? Assistant:
In a week, he orders 10 * 300 = 3000 apples.
When 3/4 of the stock is sold, the total amount of apples sold becomes 3/4 * 3000 = 2250 apples.
The amount of apples remaining is 3000 - 2250 = 750 apples.
