9) 237 students went on a field trip. Ten buses were filled and 17 students traveled in cars. How many students were in each bus?

## Step 1<br />First, we need to find out how many students traveled by bus. We know that the total number of students is 237 and 17 students traveled by car. So, we subtract the number of students who traveled by car from the total number of students.<br />### \(237 - 17 = 220\)<br />## Step 2<br />Next, we need to find out how many students were in each bus. We know that there were 10 buses. So, we divide the number of students who traveled by bus by the number of buses.<br />### \(220 ÷ 10 = 22\)
