body-mass index, or bmi, takes both weight and height into account when assessing whether an individual is underweight or overweight. bmi varies directly as one's weight, in pounds, and inversely as the square of one's height, in inches. in adults, normal values for the bmi are between 20 and 25, inclusive. values below 20 indicate that an individual is underweight and values above 25 indicate that an individual is overweight. a person who weighs 180 pounds and is 5 feet, or 60 inches, tall has a bmi of 35.15. use the four-step procedure for solving variations to determine what the bmi is, to the nearest tenth, for a 185-pound person who is 6 feet 3 inches tall. is this person underweight, normal, or overweight?
