General question about growth function?

    [RESOLVED]General question about growth function?

    P=P0ekt

    I'm given that a population doubles in number in 4 hours. Does that mean the k in the function equals 0.5 per hour or should I find k from 2=e4*k ?

    I think you should use the latter.
