Question 33164: Please, please, please, explain how you get the answer, I came up with 38% and I don't think it's right
The formula used to calculate the percentage of body fat for men is:
% Body fat = (-98.42 + 4.15w – 0.082 b) / b
Where “w” is the waist measurement in inches and “b” is the total body weight in pounds
What is the body fat for a man weighing 156 pounds and waist measurement of 32 inches. Round the percentage to the nearest interger.

% Body fat = +%28-98.42+%2B+4.15w+-+%280.082%2Ab%29%29%2F%28b%29+
% Body fat = +%28-98.42+%2B+4.15%2832%29+-+0.082%28156%29%29%2F%28156%29+
% Body fat = +%28-98.42+%2B+132.8+-+12.792%29%2F%28156%29+
% Body fat = +%2821.588%29%2F%28156%29+
% Body fat = +0.138+

Given the formula, what i have done is correct. However, with the question saying round to nearest integer, i do not think my answer is correct. So i am just questioning the equation being correct.
