    Answer:

    1, 104, 539, 727 people.

    Step-by-step explanation:

    This will be an exponential function.

    The equation for such is f(x) = a(b)^{x}.

    a = initial value, in this case, 21,802.

    b = multiplier, in this case, 4.7.

    x = time, in this case, 7.

    1. Insert your variables:

    f(x) = 21,802(4.70)^{7}

    2. Solve parenthesis.

    4.7^{7} = 50,662.312

    f(x) = 21,802(50,662.312)

    3. Solve.

    (21,802)(50,662.312) = 1,104,539,727.23

    You would round you answer off, since you can’t have 23% of a person, and your answer would be 1, 104, 539, 727 people.
