My initial reaction to seeing the $20 number was that it was more than reasonable. I thought it inexpensive. Factoring polynomial problems. It's a pain to come up with them. Writing problems where the solution to a quadratic equation has to be integers are a pain. Especially if they are of the type: (x - 3) (x + 2) = (some number to make it work out nice) Generating fraction problems where the denominators don't get out of control is and having the problems with a good mix of denominators is good. I've seen some ridiculous computer generated fraction quizzes.
