Sample Run Enter job number 1234 Hours to complete 20 Rate per hour 12 Enter job number 4567 Hours to complete 40 Rate per hour 11 The difference between Job #1234 20 hours at $ 12 per hour and Job #4567 40 hours at $ 11 per hour is -20 hours Enter job number 6789 Hours to complete 30 Rate per hour 15 Enter job number 4563 Hours to complete 15 Rate per hour 20 The difference between Job #6789 30 hours at $ 15 per hour and Job #4563 15 hours at $ 20 per hour is 15 hours
