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:

When will they have the same enrollment?

What is that enrollment amount?

Answer 1

Use systems of equations:

$y = -125x + 2020$

$y = 80x + 1075$

$80x+1075=-125x+2020$

$205x=945$

x=4.61 years

1444 students
