Calculation of the Number of People in the Bus Before the First Stop

To calculate the number of people in the bus before the first stop, we need to consider the number of people who entered and exited the bus at each stop.

According to the information provided: - At the first stop, 9 people entered the bus and 6 people exited the bus. - At the second stop, 10 people entered the bus and 15 people exited the bus. - After these stops, there were 17 people remaining in the bus.

To find the initial number of people in the bus before the first stop, we can subtract the number of people who exited the bus from the number of people who entered the bus at each stop.

Let's calculate it step by step:

1. At the first stop: - Number of people who entered the bus: 9 - Number of people who exited the bus: 6 - Number of people remaining in the bus: 9 - 6 = 3

2. At the second stop: - Number of people who entered the bus: 10 - Number of people who exited the bus: 15 - Number of people remaining in the bus: 3 + 10 - 15 = -2

Since we cannot have a negative number of people in the bus, it seems there might be an error in the given information or calculation. Please double-check the numbers provided.
