Solve the problem.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. A person who weighs 163 pounds and is 67 inches tall has a BMI of 25.53. What is the BMI, to the nearest tenth, for a person who weighs 129 pounds and who is 65 inches tall?
A. 21.1 B. 21.8 C. 20.8 D. 21.5
