This post is similar to the group activity in chapter 2 of your text. In this post you will apply section 1.2 skills of evaluating algebraic expressions to calculate BMI. You will also apply your evaluation skills along with the additive and multiplicative properties of equality to demonstrate how to solve inequalities as in section 2.8 in order to calculate ideal weight range.

As stated in your book, the NIH body mass index categories are:

Body Mass Index (BMI)

Weight Status

18.5 ≤ BMI ≤ 24.9

Considered Ideal

25.0 ≤ BMI ≤ 29.9

Considered Overweight

BMI ≥ 30.0

Considered Obese

Using the formula BMI equation, where W is weight in kg and h is height in cm;

  1. Choose three subjects do not give names, use labels such as subject A, B, C. Provide each person’s age, gender, height, and weight. Show how to convert the height in inches to cm using 1 inch = 2.54 cm, and the weight in pounds to kg using 1 lb = 0.4545 kg, round cm and kg to tenths place. Show how to calculate the BMI for each subject using the formula above (round to hundredths). State each subject’s weight status.
  2. Also, for each of your subjects, using the inequality below, show how to plug in their height only and solve for W, thus producing the ideal weigh range ( round to tenths) for each subject in the form equation.

Weight range formula, plug in only the subject’s height in cm and solve for w (will be in kg.)

equation (see section 2.8 for compound inequalities).

If the person is not within their ideal range, how much weight must be gained or lost in order to achieve their ideal range?

3. Would you say that BMI is an appropriate measure of a person’s health? Why or why not?
