According to the Centers for Disease Control and Prevention www.cdc.gov, a person's Body

Mass Index B is directly proportional to his weight W in pounds and inversely proportional

to the square of his height h in inches.

(a) Express this relationship as a mathematical equation.

(b) If a person who was 5 feet, 10 inches tall weighed 235 pounds had a Body Mass Index

of 33.7, what is the value of the constant of proportionality?

(c) Rewrite the mathematical equation found in part 40a to include the value of the constant

found in part 40b and then nd your Body Mass Index.
