14. A collection of 30 coins worth $5.50 consists of nickels, dimes, and quarters. There are twice as many dimes as nickels. How many quarters are there?

I'm pretty sure there's enough information to solve this problem, I just can't figure it out. I either get fractions or negative numbers as my answer. Any help is greatly appreciated!! :-)
