Question

Mathnificent is a math tutoring service. The first year it was open, it had 7 students. If 5 new students enroll each year, which of the following equations represents how many students will be enrolled in x years?

Answer 1

An equation to represent how many students will be enrolled in x years is 5x+7. This is because they started with 7 students, which will not change, and each year they gain 5 students, which means 5 is multiplied by the years being calculated.
