Question 235882
The Body Mass Index,I,can be used to determine an individual's risk for heart disease. An index below 25 indicates a low risk. The body mass index is given by the formula:
 I = {{{(700W)/H^2}}}
 where:
 W=weight in pounds, 
and 
 H=height in inches.
;
Jerome is 70 inches tall. What weight will keep his body mass index between 20 and 28?
:
Use an index of 24, for a height of 70, find w
24 = {{{(700W)/70^2}}}
:
24 = {{{(700W)/4900}}}
:
24 * 4900 = 700W
:
117600 = 700W
W = {{{117600/700}}}
W = 168 lb should have an index of 24

:
Check on calc: enter (700*168)/70^2 = 24
