conversations.value: James creates a media empire.  He creates a movie for $2000.  Each DVD cost $6 to make.  He sells it for 2.5 times that much.  He sells 500 movies a day for 5 days a week.  How much profit does he make in 20 weeks?
  Give me a detailed solution.

conversations.value: He sold each DVD for 6*2.5=$15
  So he makes a profit of 15-6=$9
  So each day he makes a profit of 9*500=$4500
  So he makes 4500*5=$22,500
  He makes 22,500*20=$450,000
  Then after the cost of creating the movie he has a profit of 450,000-2000=$448,000
