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? 21.81
(I didn't realized there was a SECOND PART to it). Find an inequality discribing all weights that Frances can have and be in the low risk category? round lb to the nearest whole number. Thank you.

h = 73
700w/h^2 < 25
700w/73^2
700w/5329 < 25
Multiply both sides by 5329
700w < 133,225
w < 190.32
w < 190
