A country X has a population growth rate of 3%. How many years will it take the population of country X to double? Use continuous compound growth
So I used
A=Pe^.03n I know A has to be double P.
e^.03 = 1.0304543954
but now I'm lost

  1. A = 2p
    2p = Pe^rt

    2 = e^0.03t

    Ln(2) = Lne^0.03t

    Ln(2) = 0.03t

    Solve for t
