which has a total value $3.30. You have 3 times as many quarter as dimes.

Answer by Edwin McCravy(20060)   (Show Source): You can put this solution on YOUR website!
   n +    d +    q =  27
.05n + .10d + .25q = 3.30
                 q = 3d

Solve that system of three equations and get q = 9, d = 3, n = 15
