Mr. Adams has a box containing 14 coins. The coins are either quarters, nickels, or dimes. In the box are 4 quarters. There are 4 times as many dimes as nickels. How many dimes are in the box?
I just need the equation set up and I can then take it from there.
Thanks,

14=4+D+N
but D=4N so
14=4+4N+N
5N=10 solve for N, then D 
Thank you Bob.
I got dimes = 8.
