Question

The senior classes at High School A and High School B planned separate trips to the local amusement park. The senior class at High School A rented and filled 6 vans and 9 buses with 252 students. High School B rented and filled 12 vans and 3 buses with 144 students. Every van had the same number of students in it as did the buses. How many students can a van carry? How many students can a bus carry?

Answer 1

6v + 9b = 252

12v + 3b = 144

-12v - 18b = -504

12v + 3b = 144

-15b = -360

b = 24

The rest is on you.
