Answer:
A. 120(3)t = 3,240; t = 3
Step-by-step explanation:
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 [tex]3^t[/tex].
This is expressed by the equation [tex]120(3)^t = 3240[/tex]
Substituting t =3 in the above equation to get:
[tex]120(3)^3 = 120\times 27=[/tex] 3240
So the equation is true when t = 3.
Therefore, the correct answer option is A. 120(3)t = 3,240; t = 3.
