    \[Population=(initial amount)e ^{kt}\] (2,225) 2 corresponds to years Let t=years 225 correspond to population Let population=225

    Solve for k . The formula should be in terms of t.

    Yes you did. I said let 225=population 100 is initial amount. If you think about it, it doesnt make sense.

    okay so the equation is \[225=100e ^{2k}\]

    notice that you also know the point (0,100) you start with 100 = A e^(k*0) 100= A e^0 100= A that is how you know A is 100
