Calculating body-mass index (BMI) is a way to gauge whether a person should lose weight. Doctors recommend that body-mass index values fall between 19 and 25. The formula for Body mass index B is B=705w/h^2, where w is weight in pounds and h is height in inches. A patient is 6ft 2 in tall. What should his or her weight be to have a body mass index of 25? (Round to the nearest whole pound)

Ok:

h = 6ft, 2 in = 6* 12" + 2 = 74"

W is unknown and has to be evaluated.

750 w / 74

^{2}= 25 w = (74

^{2 }* 25 )/ 705 = 194. Thank you Jim . I took 750 for 705.
