There are 6 times as many dimes as quarters, and 6 times more nickels than quarters. If you have $5.70, how much money do you have in quarters?

    X Qtrs.
    6X Dimes.
    (X+6) Nickels.

    25*x + 10*6X + 5*(X+6) = 570.
    25x + 60x + 5x+30 = 570
    90x = 570-30 = 540
    X = 6 Quarters.
    Amount = 6 * $.25 = $1.50.
