Explanation:

Step1: Calcular el BMI

$$BMI = \frac{weight (lbs)}{height (in.)\times height (in.)}\times703$$
Sustituir los valores: weight = 170 lbs, height = 69 in.
$$BMI=\frac{170}{69\times69}\times703$$
$$BMI=\frac{170}{4761}\times703$$
$$BMI = 0.0357\times703$$
$$BMI\approx25.1$$

Step2: Clasificar el BMI

Buscar en la tabla para edad 14 años.
