James creates a media empire.  He creates a movie for $2000.  Each DVD cost $6 to make.  He sells it for 2.5 times that much.  He sells 500 movies a day for 5 days a week.  How much profit does he make in 20 weeks?
He sold each DVD for 6*2.5=$<T>multiply(6, 2.5)=15.0
So he makes a profit of 15-6=$<T>subtract(15, 6)=9
So each day he makes a profit of 9*500=$<T>multiply(9, 500)=4500
So he makes 4500*5=$<T>multiply(4500, 5)=22500
He makes 22,500*20=$<T>multiply(22500, 20)=450000
Then after the cost of creating the movie he has a profit of 450,000-2000=$<T>subtract(450000, 2000)=448000
