conversations.value: Can you break down the solution for me for this math problem: James decides to buy a living room set.  The coach cost $2500 and the sectional cost $3500 and everything else has a combined cost of $2000.  He gets a 10% discount on everything.  How much did he pay?

conversations.value: The combined cost of everything was 2500+3500+2000=$8000
  So he gets an 8000*.1=$800 discount
  That means he pays 8000-800=$7200
