Tonya is in a hamburger eating contest. Each hamburger is 4 ounces. Last year the winner ate 84 ounces. How many hamburgers does she have to eat to beat last year's winner?
Last year's winner ate 21 hamburgers because 84 / 4 = <T>divide(84, 4)=21.0
She needs to eat 22 hamburgers because 21 + 1 = <T>add(21, 1)=22
