Problema Solution

76 inches tall. What weights will keep his body mass index between 25 and 33?

The formula for the body mass index

This should be 25 <= BMI <= 33, where BMI = (mass * 703) / 762 , so

25 <= (mass * 703) / 762 <= 33

25 * 762 <= mass *703 <= 33 * 762

144400 <= mass * 703 <= 190608

144400/703 <= mass <= 190608/703

205.40 <= mass <= 271.13

So, his weight should be between 205.4 and 271.13 pounds
