9) For a field trip 12 students rode in cars and the rest filled seven buses.How many students were in each bus if 36 students were on the trip?

## Step 1<br />First, we need to find out how many students rode in the buses. We know that 12 students rode in cars and the total number of students on the trip was 36. So, we subtract the number of students who rode in cars from the total number of students.<br />### \(36 - 12 = 24\)<br />## Step 2<br />Next, we need to find out how many students were in each bus. We know that the remaining students filled seven buses. So, we divide the number of students who rode in the buses by the number of buses.<br />### \(24 \div 7 = 3.42857142857\)
