Answer:
3. about 2 students per year
Explanation:
The rate of change would be the difference in the number of students divided by the number of years passed.
So, rate of change =
![(356-305)/(2019-1998)](https://img.qammunity.org/2022/formulas/mathematics/high-school/ifbtns72oft0ehmhb93b1j0bxhhs0zp306.png)
=
![(51)/(21) = 2.43](https://img.qammunity.org/2022/formulas/mathematics/high-school/aaz96xhnh70v15qiounwh6yxrp9lnd7ebd.png)
So it's around 2 students per year.
I hope this is correct and helps!
