  1. d+n=34

    .10d+.05n=2.90

    n=34-d

    .10d+.05(34-d)=2.90

    .10d+1.70-.05d=2.90

    .05d+1.70-1.70=2.90-1.70

    .05d=1.20

    d=24

    n=10


  2. I agree with the first answer. 24 dimes and 10 nickels.

  3. 24 dimes

    10 nickels

  4. Where do you find riddles like this? They're so hard, but make you think!!
