Question 146204: 4) The body mass index I can be used to determine an individuals risk for heart disease. An index less than 25 indicates a low risk. The body mass index is given by the formula, or model where w=weight, in pounds and h=height in inches. Jerome is 71 inches tall.
What weights will keep his body mass index between 22 and 33?

Start with the given equation
Plug in
Square 71 to get 5,041
Since we want the body index to be in between 22 and 33, this means we must construct the following inequality
Multiply all sides by 5,041
Multiply
Divide all sides by 700 to isolate w
Divide
So he must be within 158 and 238 pounds to have a body mass index between 22 and 33 (I rounded to the nearest pound)
