conversations.value: I'm stuck on this math problem: Tom broke his leg and needed to go to the doctor.  The visit cost $300 and the cast cost $200.  If insurance covered 60% how much was Tom's out-of-pocket cost?
  Can you help?

conversations.value: The cost was 300+200=$500
  So insurance paid for 500*.6=$300
  That means he had to pay 500-300=$200 out of pocket
