On Monday, 217 students went on a trip to the zoo. All 5 buses were filled and 7 students had to travel in cars. How many students were
in each bus ?

To figure out this equation, let's break it down

there were 217 students

5 buses

7 students left over

first we need to take away the 7 students from the 217 students total so we are left with an even number.

217 - 7 = 210

and since there were 5 buses filled with students we divide by 5 (assuming they all hold the same capacity)

210 ÷ 5 = 42

there were 42 students in each bus

Hope this helped! :D
