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
Answer choice C would be correct since both sides are increasing at a set rate, x is increasing by one while y is increasing by 2 every time. Hope this helps :)
