    Answer: the population will be

    395925972

    Step-by-step explanation:

    The growth rate is exponential. We would apply the formula for exponential growth 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 = 100000000

    r = 3.5% = 3.5/100 = 0.035,

    t = 40 years

    Therefore

    A = 100000000 (1 + 0.035) ^40

    A = 100000000 (1.035) ^40

    A = 395925972
