Body Mass Index More and more people are becoming health conscious. They worry about their fat intake, the number of calories consumed and their overall weight. Young people tend to be slim and trim were as older people begin to form that pot belly and may look a little over weight. As a person gets older they become less active and therefore gaining a few pounds is normal. However, when is normal not normal at some point one must realize that I am getting too fat and do something about. The body mass index can help a person determine whether he / she is within normal range of their body weight. To determine what the correct weight a person should be in comparison to his / her height we must use the Body Mass Index formula (BMI). The formula is BMI = 703 x weight / height squared. In my equation “W” will represent the weight and “H” will represent the height. The discussion gives four different intervals to calculate the equation to determine if a person is within range of the desired weight, has a chance of living a longer life because of weight, overweight and obese. I will substitute my weight 200 pounds and my height 67 inches in place of the variables “W” and “H.” 1. The following interval shows weight that a person may have a chance of living a longer life. I will solve the equation explaining the step as I go. 17 < BMI < 22 This is the first interval of I will solve. This interval contains a compound inequality were the three values are less than the next. 17 < (703W / H2) < 22 I replaced BMI with 703 this is an equivalent inequality for BMI. The part of the equation was placed in parenthesis because it needs to be done first. 17 < (703W / 672) < 22 In this step of the compound equation I plugged in my height to replace H2. 17 < (703W/4489) < 22 I started simplifying the equation by squaring my height.
