While cleaning out the closet, john found of coins. The box contained nickels,
dimes, and quarters. He added up the change and found that there were 85 coins
totaling $6.25 in the in the box. If there were 3 times as many nickels as
dimes, how many quarters were there? 

   n +    d +    q = 85         <----- the coin equation 
.05n + .10d + .25q =  6.25      <----- the money equation
                 n = 3d         <----- 3 times as many nickels as dimes.

Can you solve that system? If not post again asking how.

Answer: 60 nickels, 20 dimes, and 5 quarters.
