    Answer: the population after 9 years is 17175

    Step-by-step explanation:

    We would apply the formula for exponential decay which is expressed as

    A = P (1 - r) ^ t

    Where

    A represents the population after t years.

    t represents the number of years.

    P represents the initial population.

    r represents rate of growth.

    From the information given,

    P = 24800

    r = 4% = 4/100 = 0.04

    t = 9 years

    Therefore,

    A = 24800 (1 - 0.04) ^9

    A = 24800 (0.96) ^9

    A = 17175
