pat is five feet tall and weighs 100 pounds

overweight
underweight
normal
?amir
?pat
?julie

Explanation:

Step1: Convert height to inches

• Amir: \(5\times12 + 9=69\) inches
• Julie: \(5\times12+7 = 67\) inches
• Pat: \(5\times12=60\) inches

Step2: Calculate BMI for Amir

$$BMI=\frac{120\times703}{69^{2}}=\frac{84360}{4761}\approx17.7$$

Since \(17.7<18.5\), Amir is underweight.

Step3: Calculate BMI for Julie

$$BMI=\frac{170\times703}{67^{2}}=\frac{119510}{4489}\approx26.6$$

Since \(25 < 26.6<30\), Julie is overweight.

Step4: Calculate BMI for Pat

$$BMI=\frac{100\times703}{60^{2}}=\frac{70300}{3600}\approx19.5$$

Since \(18.5 < 19.5<25\), Pat is normal.

Answer:

Amir: Underweight, Pat: Normal, Julie: Overweight
