A. 120(3)t = 3,240; t = 3
<u>Step-by-step explanation:</u>
We are given that enrollment capacity for first year = 120
The school plans to triple the capacity every year.
Assuming t to be the number of years, the capacity for every t year will be .
This is expressed by the equation
Substituting t =3 in the above equation to get:
