Answer:
54
Step-by-step explanation:
If 5 students went in cars then 216 students were in the buses (221-5=216)
There were four buses so divide 216 by 5 which is 54.
So there were 54 students in each bus
If you have 221 students going to the zoo and 5 that went to the zoo in cars you only need to account for the 216 travelling by bus. So you subtract 5 from 221 and divide what you have left over (216) by 4 for the 4 buses you're using.
216/4= 54
