Question 138535: 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 176pounds and stands 68 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.
Francis approximate body mass index is??
Can someone help me with this??

BMI is given by I=+700+W%2FH%5E2
Francis weighs 176 pounds and is his height is 68 inches.
Since the value for W and H are in the correct units (pounds and inches), just replace the variables in the BMI equation with Francis's info.
I=+700+W%2FH%5E2
I+=+%28700%2A+176%29%2F68%5E2
I+=+26.64 too bad Francis.
He can get into the low risk group as long as:
25+=%28700%2AW%29%2F68%5E2
%2825+%2A+68%5E2%29%2F700+=+W+
165.14+=+W+
So if Francis can lose 10 pounds, he can save a few bucks and live a more healthy life. He need to weigh less than 165 w%3C165
