Question

select the correct answer.
sapphron is 60 inches tall and weighs 90 pounds.
use the formula below and a calculator to answer the question about her weight.
bmi = weight (in pounds) ÷ height (in inches)² × 703
which bmi category fits sapphron?
a. 25.2, overweight
b. 17.5, underweight
c. 18.6, appropriate weight

Explanation:

Step1: Identify given values

Weight \( W = 90 \) pounds, Height \( H = 60 \) inches.

Step2: Substitute into BMI formula

BMI formula: \( \text{BMI} = \frac{W}{H^2} \times 703 \)
Substitute \( W = 90 \), \( H = 60 \):
\( \text{BMI} = \frac{90}{60^2} \times 703 \)

Step3: Calculate \( H^2 \)

\( 60^2 = 3600 \)

Step4: Calculate fraction

\( \frac{90}{3600} = \frac{1}{40} = 0.025 \)

Step5: Multiply by 703

\( 0.025 \times 703 = 17.575 \approx 17.5 \)

Step6: Determine BMI category

BMI of 17.5 is underweight (since underweight is typically BMI < 18.5, appropriate is 18.5 - 24.9, overweight ≥ 25).

Answer:

B. 17.5, underweight
