Question 205548
The body mass index, I, can be used to determine and 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, where w=weight, in pounds, and H=height, in inches. Frank weighs 170 pounds and stands 68 inches tall. What is his approximate body mass index? Find an inequality describing all weights that Frank can have and be in the low riskt category.
-------------
I = 700*170/68^2 = 25.74
-------------------------
If I < 25 then:
700*w/68^2 < 25
w < 25*68^2/700
w < 165.14
