Tim hires two bodyguards.  They each charge $20 an hour.  He hires them for 8 hour per day.  How much does he pay them in a week if he hires them 7 days a week?
It cost him 20*2=$<T>multiply(20, 2)=40 an hour for both of them
That means he pays 40*8=$<T>multiply(40, 8)=320 a day
So he pays 320*7=$<T>multiply(320, 7)=2240 a week
