You can put this solution on YOUR website! An index less than 25 indicates a low risk.
The body mass index is given by the formula, I=700w/H^2,where weight
W= weight,in pounds,and H= Height,in inches.
-------------------
Francis weighs 170 pounds and stands 73 inches tall. What is his approximate body mass index?
I = 700*170/73^2
---
I = 22.33..
===============================
----------------------------------
Find an inquality describing all weights W that Francis can have and be in the low risk category.
Solve 700*w/73^2 < 25
---
w < 190.32 lbs.
