Calculation of the Number of Passengers in the Bus

To calculate the number of passengers in the bus before the first stop, we need to consider the passengers who got off and those who got on at each stop.

Let's break down the information provided:

- At the first stop, 7 passengers got off and 4 passengers got on. - At the second stop, 6 passengers got off and 13 passengers got on. - After the second stop, there were 38 passengers in the bus.

To find the number of passengers in the bus before the first stop, we can work backward from the information given.

Let's assume the number of passengers in the bus before the first stop is x.

- At the first stop, 7 passengers got off, so the number of passengers in the bus decreased to x - 7. - Then, 4 passengers got on, so the number of passengers increased to (x - 7) + 4 = x - 3. - At the second stop, 6 passengers got off, so the number of passengers decreased to (x - 3) - 6 = x - 9. - Finally, 13 passengers got on, so the number of passengers increased to (x - 9) + 13 = x + 4.

According to the information provided, after the second stop, there were 38 passengers in the bus. Therefore, we can set up the equation:

x + 4 = 38

To find the value of x, we can solve this equation:

x = 38 - 4 = 34

Therefore, there were 34 passengers in the bus before the first stop.
