Note: There are 315 students in all. The expression being created will equal this amount.
11 of the students rode in cars, so they will be excluded from the bus amount. Add those at the end (+11).
It is given to us that there are 8 buses in all. You are solving for the amount of students in each bus, which is signified by x. As there are 8 buses, you will multiply the two together: 8x
To solve this, I would square root all of the possible answers and see which ones the arrow falls between. After that I would choose the answer closest to it.
