To find out how many students were on each bus, we need to set up an equation based on the information provided.
- First, we know that there are 449 students in total.
- All 9 buses were filled with students, and we have 8 students that had to travel in cars. Therefore, the total number of students that went on the buses is: \[ 449 - 8 = 441 \]
- Let \( x \) represent the number of students on each bus. Since there are 9 buses, the total number of students on the buses can be represented as: \[ 9x = 441 \]
Now, we can solve for \( x \): \[ x = \frac{441}{9} = 49 \]
So, the number of students on each bus is: \[ \boxed{49} \]
