conversations.value: Solve the math problem: Claudia offers art classes to kids and charges $10.00 for her one-hour class.  If 20 kids attend Saturday’s class and half that many attend Sunday’s class, how much money does she make?

conversations.value: Sunday’s class is half the size of Saturday’s class with 20 kids so Sunday has 20/2 = 10 kids
  She has 20 kids on Saturday and 10 kids on Sunday for a total of 20+10 = 30 kids
  She charges $10.00 per kid and teaches 30 kids over the weekend so she makes 10*30 = $300.00
