If a 155-lb man bicycles at a moderate rate of 12 to 13.9 mph, he burns about 45 calories per mile. If he lives 1.4 miles from campus and commutes round trip eighty-four days per semester, how many pounds lighter will he be at the end of the semester than if he had driven to class? (3500 calories of energy are in one pound of fat.) Express your answer in pounds to three significant figures.
