<PRE><B>Question 15625</B>
Let number of quarters be q.
Then number of dimes is 3q.
And number of nickels is q+3
Value of quarters is 25q cents
Value of dimes is 10(3q) = 30q cents
Value of nickels is 5(q+3) = 5x+15 cents
EQUATION
Value of nickels + Value of dimes + Value of quarters  = 255 cents
      5x+15 + 30q + 25q = 255
                60q  = 240
                  q  = 4 (number of quarters)
                 3q  = 12 (number of dimes)
                q+3  = 7 (number of nickels)
