    this is simply asking for N(10) and N(60), since that gives the number of bacteria after 10 and 60 minutes respectively, as that is how N(t) was defined

    can you continue?

    So I'd do something like this?

    N(10) = 4000(2)^10/20
    N(60) = 4000(2)^60/20

    to be safe, type 2^(10/20) and evaluate first, then multiply the answer by 4000. a similar thing for the 2nd one

    half an hour? wow
