    Let P be your population after x years with an annual growth rate of "m" and a starting population of A: P = A(1 + m)^x

    The factor: (1 + m)^x comes from after year one: (1 + m) after year 2: (1 + m)^2 year3 : (1 + m)^3 because of [(1 + m)^2](1 + m) etc.

    So, you can put in 295 for A, 0.07 for m, and your years for "x"

    The exponential aspect of the equation comes from having an expression to a power with "x" in it.

    For your purposes, you'll be wanting to make "x" equal to 2.
