Lizzy: 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 = $40 an hour for both of them. That means he pays 40 * 8 = $320 a day. So he pays 320 * 7 = $2240 a week. Final answer: 2240.
