b) 114.7 lbs
c) 118.9 lbs
d) 121.2 lbs

Answer :

Final answer:

The Hamwi formula is used to estimate the ideal body weight based on height and frame size. The ideal body weight for the given individual is 114.7 lbs. The correct option is b) 114.7 lbs.

Explanation:

The Hamwi formula is a method used to estimate the ideal body weight (IBW) based on an individual's height and frame size. For females, the formula is: IBW = 100 lbs + (5 lbs x each inch over 5 feet). In this case, the woman is 62 inches tall, which is 2 inches over 5 feet. So, her IBW would be 100 lbs + (5 lbs x 2 inches) = 100 lbs + 10 lbs = 110 lbs.

However, since she has a small frame, her IBW is adjusted down by 10%, resulting in an IBW of 110 lbs - (10% x 110 lbs) = 110 lbs - 11 lbs = 99 lbs. Since her actual weight is 116 lbs, which is higher than her IBW, we can conclude that the answer is b) 114.7 lbs, which is the closest option to her actual weight.

Therefore The correct option is b) 114.7 lbs.
