1. I posted the answer only a few minutes after you posted the restriction. How fast do you think I can type. Patience, please.

3. Ahh I'm so sorry! I only posted it again because I realized that I accidentally posted it in the answers section and not the question section.

4. That's the way you are supposed to do follow ups. I always check to see if there is a follow up. I think al of the volunteers do that although the time it takes us to get back varies according to how busy we are and how much time we have to spend answering questions. Hope you understood how to solve the problem. You might want to check and see if you get the same answer with this way vs the HH way. The HH way makes the same assumptions I suggested you make to keep from solving a quadratic.
