Question

if ramona weighs 200 pounds and is 57\, what is a reasonable target weight for weight loss? remember that you divide inches by 39.7 to convert to meters and divide weight in pounds by 2.2 to convert to kilograms.
o a. 127 pounds
o b. 147 pounds
o c. 167 pounds
o d. 187 pounds

Explanation:

Step1: Calculate height in inches

Since 1 foot = 12 inches, 5 feet 7 inches = \(5\times12 + 7=67\) inches.

Step2: Calculate height in meters

Divide inches by 39.7: \(h=\frac{67}{39.7}\approx1.69\) meters.

Step3: Calculate a reasonable weight range

A common formula for a healthy weight range is \(BMI = 18.5 - 24.9\). Using \(BMI=\frac{weight(kg)}{height(m)^2}\).
For \(BMI = 18.5\), \(weight(kg)=18.5\times(1.69)^2\approx18.5\times2.86 = 52.91\) kg. Convert to pounds: \(52.91\times2.2\approx116.4\) pounds.
For \(BMI = 24.9\), \(weight(kg)=24.9\times(1.69)^2\approx24.9\times2.86 = 71.21\) kg. Convert to pounds: \(71.21\times2.2\approx156.7\) pounds.
Looking at the options, 147 pounds is within a reasonable range close to these calculations.

Answer:

B. 147 pounds
