conversations.value: James decides to replace his car.  He sold his $20,000 car for 80% of its value and then was able to haggle to buy a $30,000 sticker price car for 90% of its value.  How much was he out of pocket?
  Give me a detailed solution.

conversations.value: He sold his car for 20000*.8=$16,000
  He bought the new car for 30,000*.9=$27,000
  That means he was out of pocket 27,000-16,000=$11,000
