Question

Jameston High School has 2020 students.  Its enrollment has been decreasing at a rate of 125 students per year.  Townsville High School has 1075 students.  Its enrollment has been increasing at a rate of 80 students per year. Assuming the enrollment rates continue:

A.	Write an equation to model this.

B.	When will they have the same enrollment?

C.	What is that enrollment amount?

Neil · Answer

A. Jameston High School Enrollment: 125n - 2020

Townsville High School Enrollment: 80n + 1075

B. 125n - 2020 = 80n + 1075

C. Solve B's equation, then the answer you get, plug that in for n to get the enrollment amount.

Sorry, I made messed up entirely.

A. Jameston High School Enrollment: 2020 - 125n

Townsville High School Enrollment: 1075 + 80n.

B. To find out when they will have the same enrollment would be: 2020 - 125n = 1075 + 80n

Solve 2020 - 125n = 1075 + 80, to get 2020 = 1075 + 205n, solve that further.

I'm sure you know what to do from there. Sorry for the confusion.
