The body mass index, I, can be used to determine an individual's risk for heart disease. An index less than 25 indicates a low risk. The body mass index is given by the formula, or model,I= 700 W/H2(little 2 over the H) , where W=weight, in pounds, and H=height, in inches. Francis weighs 162 pounds and stands 73 inches tall. What is his approximate body mass index? Find an inequality describing all weights W that Francis can have and be in the low-risk category.

The body mass index, I, can be used to determine an individual's risk for heart disease. An index less than 25 indicates a low risk. The body mass index is given by the formula, or model,I= 700 W/H2(little 2 over the H) , where W=weight, in pounds, and H=height, in inches. Francis weighs 162 pounds and stands 73 inches tall. What is his approximate body mass index? Find an inequality describing all weights W that Francis can have and be in the low-risk category.

1) the value of the height will not change for Francis so you can substitute that value into the equation right away and maybe reduce the constants as well.
2) Figure out if 162 as the weight is in the low-risk category

3) I would then state that I = 25, and evaluate for the unknown W in the equation; this gives you the maximum weight Francis can be and still be within the low-rist category.

This is how I solve this kinds of problems.  Another thing you could do is graph this equation.
