To find out how many students were on each bus, follow these steps:

1. Total students who traveled by buses: Subtract the students who traveled in cars from the total number of students: $449 - 8 = 441$

2. Students per bus: Divide the total number of students traveling by bus by the number of buses: $441 \div 9 = 49$

Thus, 49 students were on each bus.
