Question

For a field trip 4 students rode in cars and the rest filled nine buses. How many students were in each bus if 472 students were on the trip?

Answer 1

`52` students were in each bus.

Explanation:

First, you start with the equation:

`9x + 4 = 472`

Since four students rode in cars, you want to eliminate this part of the problem to find how many students actually rode in the buses

So you would subtract `4` from both sides and get:

`9x = 468`

Finally, you would divide both sides by `9` and get `52` students on each bus
