"The cost of an SAT prep class for q students is 700-10q per student. If the SAT prep company wants to maximize it's profit, how many students must sign up and what price will each student pay?"
I don't just want the answer, I need to know how to do the problem.

Edited by H2O: 12/5/2014 1:06:07 PM700 - 10q is your function. Use first and second derivatives to do an optimization. I can do the math later to see if there's something missing. I need practice for my final anyway Edit: As far as missing information goes, I don't immediately see a constraint equation, but I could very easily be overlooking something.
