Question 183082
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/H^2, where W = weight, in pound's, and H = height, in inches.
------------------------------

Jerome is 75 inches tall. What weights will keep his body mass index between 25 and 33? 
---
25 < I < 33
25 < 700w/H^2 < 33
H = 75 so you get:
25 < 700 w/75^2 < 33

25*75^2 < 700 w < 33*75^2

(25*75^2)/700 < w < (33*75^2)/700

200.893 lbs. < weight < 265.179 lbs.

Jerome's body mass index will fall between 25 and 33 for the set of all weights such that ____< W < ____. 
(round to the nearest whole number as needed)
