    doubling time

    A study shows the doubling time of bacteria is 15 days. If we assume exponential growth A=Ao(1+i)^t, where t is given in days, find the growth constant i.

    I found .0473, but im not very sure and would like someone to check it for me.

    Correct!

    (I've got i = 0.047294122...)
