conversations.value: Jacoby wants to save money for a trip to Brickville. He needs to have $5000 total to go on his trip. He works a job earning $20 per hour and works 10 hours. He then finds he can sell cookies for $4 each, and he sells 24 pieces of cookies. With the money he has so far, he buys a lottery ticket for $10 and wins $500. Finally, he gets $500 from both of his sisters as a gift. How much more, in dollars, does Jacob need to go to Brickville?
  Work out the solution step by step.

conversations.value: Jacob earns $20 per hour * 10 hours = $200 for working.
  So he earns $4 each * 24 = $96 for the cookies.
  So far he has earned $200 + $96 = $296.
  He buys a lottery ticket so $296 - $10 = $286 was left in his money.
  After winning in a lottery, he had a total of $500 + $286 = $786.
  He gets $500 * 2 per sister = $1000 from her sisters.
  So he has so far $1000 + $786 = $1786.
  He needs $5000 - $1786 = $3214.
