please help . plot population size... biology?

Over the course of 25 years, a human population from a small island off the coast of Virginia grew from 100 to 250 people. Figure out how big the population might be after 50, 75, and 100 years. Plot the population size at 0, 25, 50, 75, and 100 years

    You can just assume 1st Order growth (ie. that the rate of increase is proportional to the population size). This is realistic as long as there is more than enough food and land to sustain the growing population.

    The equation will be:

    P(t) = 100 e^-kt

    and one of the solutions is:

    250 = 100 e^-k(25)

    you can solve for k and then solve for the population for any t.
