Final answer:
The starting amount of apples is 4440. After the calculation, will get the number of apples left is 2699.
Step-by-step explanation:
To find out how many apples were left, we need to subtract the number of apples sold from the total number of apples.
The supermarket started with 30 crates, and each crate had 148 apples, so the total number of apples at the beginning was: 30 * 148 = 4440.
In the morning, the supermarket sold 835 apples, and in the evening, they sold 906 apples.
Therefore, the total number of apples sold was: 835 + 906 = 1741.
To find the number of apples left, we subtract the apples sold from the starting amount:
4440 - 1741
= 2699 apples.
