    I'm sorry about the other post. I didn't post it. Whoever did post it will not be posting again on this board.

    I'm sorry, but I can't help you with this question, but I'm sure someone will show you how to do it.

  • algebra -

    let the number of nickels be x
    let the number of pennies be x+12
    let the number of dollar bills be x-5

    now we will think of the "value" of our money
    1(x+12) + 5(x) + 100(x-5) = 996

    solve for x
    let me know what you got.

  • algebra -

    996=5n+p+100d
    12+n=p
    n-5=d

    n=nickels
    p=pennies
    d=dollars

    996=5n+(12+n)+100(n-5)
    1484=106n
    n=14

    p=12+n=12+14=26
    d=n-5=14-5=9

    double check
    996=5(14)+26+100(9)
    996=996

    hope this helps
