Question

The school population for a certain school is predicted to increase by $60$ students per year for the next $20$ years. If the current enrollment is $800$ students, what will the enrollment be after $20$ years?

Answer 1

Compute the required value:

Given: Current enrollment $=800$

Increase in the enrollment of students per year $=60$

So, increment in the enrollment of students after $20$ years $=60\times 20$

$=1200$

Now, total enrollment of students after $20$ years $=$Current enrollment $+$Increment in enrollment of student

$=800+1200$

$=2000$

Hence, the enrollment after $20$ years will be $2000$.
