Problema Solution

Elanie's height is 67 inches. Determine, in terms of an inequality, those weights "W" that will keep her body mass index below 25.

Write an inequality and solve.

Answer provided by our tutors

BMI = (mass in lb) * 703 / (height in inches)^2

So,

25 > BMI = (mass W in lb) * 703 / (67)^2

means 

25 > W*703 / 67^2

25*67^2 / 703 > W

W < 112225/703 (in lb)

round off to whatever digit is desired...
