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.

helper,
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
