Mike gets paid 100 dollars a week.  He decides to spend half of that at an arcade.  He spends 10 dollars at the arcade on food and uses the rest on arcade tokens. He can play for 1 hour for $8. How many minutes can he play?
He spent 100*.5=$<T>multiply(100, 0.5)=50.0 at the arcade.
He uses 50-10=$<T>subtract(50, 10)=40 on tokens
He can play 40/8=<T>divide(40, 8)=5.0 hours
There are 60 minutes in an hour so he can play 5*60=<T>multiply(5, 60)=300 minutes
