On a 14day 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 total calories consumed
28 * 666 = 18,648 total calories used
I think you can take this problem from here.
