Question

The function C(t) = 400 + 30t models the number of classrooms, C. in the town of Sirap, t years from
now. The function D(t) = 25 + t models the number of students per classroom, D, t years from now.
Let S be the number of students in Sirap’s school system t years from now.

2 ) Write a formula for S(t) in terms of Ct) and D(t).

1 ) Write a formula of S(t) in terms of t.

    Answer:

    S(t)=C(t)×D(t)

    S(t)=30t^{2}+1150t+10000

    Answer:

    1) S(t) = C(t) × D(t)

    2) S(t) = (400 + 30t)(25 + t)

    Step-by-step explanation:

    The function C(t) = 400 + 30t ……….. (1), models the number of classrooms, C. in the town of Sirap, t years from  now.  

    The function D(t) = 25 + t ……… (2) models the number of students per classroom, D, t years from now.

    Then if S(t) represents the number of students in Sirap’s school system t years from now, then, we can write the relation  

    1) S(t) = C(t) × D(t) (Answer)

    2) Hence, the formula of S(t) in terms if t is given by  

    S(t) = (400 + 30t)(25 + t) (Answer)
