Calculating the Number of People Entering the Bus

To calculate the number of people who entered the bus at the first stop, we can use the information provided and work through the steps.

1. Initial State: - At the first stop, the bus is empty.

2. Second Stop: - 10 people enter the bus.

3. Third Stop: - 12 people exit the bus, leaving 17 people on the bus.

Calculation

Let's calculate the number of people who entered the bus at the first stop.

- Initial state: 0 people - Second stop: 10 people enter - Third stop: 12 people exit, leaving 17 people on the bus

To find the number of people who entered at the first stop, we can use the equation: Number of people at the third stop = Number of people at the second stop + People who entered at the first stop - People who exited at the third stop

So, 17 = 10 + x - 12 Solving for x, we get: x = 17 + 12 - 10 x = 19

Conclusion

Therefore, 19 people entered the bus at the first stop.
