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=700w/h2, which wheight in inches. Frances weighs 166 pounds and stands 73 inches tall. Which is his approximate body mass index?

If this is the formula (Note h^2 means 'h squared' and use of parentheses)
w = 166, h = 73
I = 700w/(h^2)
I = 700(166)/(73^2)
I = 116,200/5329
I = 21.81 
BMI= 703*w/h^ 2
BMI 703*130/55inch^2
BMI= 703*120/3844
BMI= 21.94 
BMI= 703*w/h^ 2
BMI 703*130/55inch^2
BMI= 703*130/3844
BMI= 
23.77
