On a 14-day vacation, Glenn increased his caloric intake
by 1500 calories per day. He also worked out more than
usual by swimming 2 hr a day. Swimming burns 666 calories
per hour, and a net gain of 3500 calories adds 1 lb of
weight. Did Glenn gain at least 1 lb during his vacation?
14 * 1500 = 21,000 additional calories
2 * 666 * 14 = 18,648 calories burned
He ate 2,352 more calories than he burned.
