You would need to take the amount of money earned ($740) and divide it by the number of hours worked (40). In this case, you get $18.50 per hour. Then, you need to multiply the hourly payment by 32 to find out how much money Tammy earns in 32 hours. In this case, Tammy earns $592 in 32 hours (since $18.50 * 32 = $592).
