In the United States, an overweight person is defined as anyone with a “body mass index” (or BMI) of 27.6 or higher. The World Health Organization defines an overweight person as one with a BMI of 25 or higher. To determine BMI, multiply your weight in pounds by 703, and then divide that result by your height (in inches) squared. Write this in formula form using w for weight in pounds and h for height in inches. Calculate the BMI (rounded to the nearest tenth) for each of these people:

a. 5 ft 5 in., 165 lb

b. 6 ft, 185 lb

c. What is the weight (rounded to the nearest pound) of a 5-ft, 6-in. tall person with a BMI of 25?
