use the formula below and a calculator to answer the question about her weight.
bmi = weight (in pounds) ÷ height (in inches)² x 703
which bmi category fits sapphron?
17.5 underweight
25.6 overweight
30.2 obsese

Explanation:

Step1: Substitute values into formula

Given \( \text{Weight} = 90\) pounds and \( \text{Height}=60\) inches. Substitute into \( \text{BMI}=\frac{\text{Weight}}{[\text{Height}]^{2}}\times703\). So \( \text{BMI}=\frac{90}{60^{2}}\times703\).

Step2: Calculate denominator

First, calculate \(60^{2}=60\times60 = 3600\). Then the formula becomes \( \text{BMI}=\frac{90}{3600}\times703\).

Step3: Simplify fraction

\(\frac{90}{3600}=\frac{1}{40}\) (since \(90\div90 = 1\) and \(3600\div90=40\)). Now \( \text{BMI}=\frac{1}{40}\times703\).

Step4: Calculate final value

\(\frac{703}{40}=17.575\approx17.5\)

Answer:

17.5 underweight
