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?

1 answer

14 * 1500 = 21,000 additional calories

2 * 666 * 14 = 18,648 calories burned

He ate 2,352 more calories than he burned.
