Don't worry, I figure out problems just after I ask for help in them as well. It's really annoying. Still, well done for figuring it out on your own. I might as well tell you what I got so you can check your answer and this topic will have some use.
Julie should have 11 quarters and 8 nickels.
Although you could just make two simultaneous equations for this question, I find it easier to assume that she has all nickels and then work out how many she would have to exchange for quarters to get the right amount.
So, 19 nickels would give her $0.95, which is $2.20 short of her target. Exhanging a nickel for a quarter adds $0.20 to her amount, which means that she needs to do that 11 times. Therefore, she has 11 quarters and then the number of nickels left is easy to work out.
