Math question help please!

  1. I am doing a math work sheet to help prepare for my upcoming semester in school and I need help with a math problem.

    Question is....

    The HCP prescribes 1.7 mcg/kg/body weight/day. Client's weight is 150 lbs.

    What is the dose of medication ? ( round to nearest hundredth.)

    I tried 115.91 and it is incorrect
    150/2.2=68.18
    68.18*1.7=115.91(rounded)

    Can someone please show me how this problem is done.


    Thank you!

    were you given the correct answer? How far off was your answer?

    Me thinks that your answer sheet is in error.

    Sorry for the confusion but that's the answer I came up with and they said it's incorrect, I still
    do not have the correct answer because I can not see the answer on the computer until I answer it correctly.

    No I do not have the correct answer that's what I'm searching for now.

    I wonder if they're being picky about significant digits? Strictly speaking, you shouldn't be rounding to a hundredth of a kilo because you don't know what hundredth of a pound you have. Maybe try 150/2.2 = 68 kg, then 68*1.7 = 115.6?

    uhmmmm - the only other possibilities that I could think of would be that the answer may be converting the units from mcg to mg... or maybe dividing the total into equal doses (tid, bid?) and the answer would be how much each dose should be.... and like someone else pointed out, the answer key could just be wrong.

    No not the correct answer either

    115.60? If they really want it to the hundredth?

    Also, please use the "quote" button so we know who you're responding to, when you say an answer is wrong.

    Try no rounding of anything until the end. I got 115.66613 mcg/day. So try 115.7 or 115.67.
