Real-Life Problem

Ms. Cookie conscientiously deletes ALL memory from her calculators: RAM, ROM, RIM, ROOM, and all the excellent APPS on the "school bus yellows" for the TAKS test. Ms. Cookie saved one calculator to the side and kept the programs/APPS on there. Ms. Cookie now wants to repopulate the other calculators. Once she does one, then she has 2, then 4, etc. Each repopulation takes 12 minutes (!!!! who knew!!!!). How long will it take her to "fix" all 74 calculators?

    Maybe it would be better to start with 84 calculators?

    That would provide you with a great "hey, does this always work?" moment -

    and importantly, one where the kids can quickly verify that the answer is "no." They never get enough of those.


  2. I guess I'm being slow this morning. I don't understand the 84 vs 74 issue since in my mind it is the 1,2,4,8,.... pattern.

    And maybe I can add to the mix: Ms. Cookie only has 15 cables (haven't counted, though).

    If you have TI84s you can disable the Apps rather than delete them.

    Sorry for never getting back on this.

    With your set-up, 84 TI-84s would take 84 minutes to reinstall.

    It is a silly conjecture (would 74 take 74 minutes?) but nice when they can say, "no, that pattern does not work."
