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