Answer :

Main Answer:

The male's weight loss equates to 100% of his ideal body weight, as he is now 87.91% of his initial weight. c. 100%.

Therefore, The correct answer is c. 100%.

Explanation:

The individual's percent of ideal body weight is calculated by comparing the current weight to the initial weight. In this case, the male's current weight is 189 pounds, and six months ago, he weighed 215 pounds. To determine the percent of ideal body weight, you need to find the percentage reduction from the initial weight to the current weight. Subtract the current weight from the initial weight, then divide that difference by the initial weight, and finally, multiply by 100.

The calculation is as follows:

[tex]\[ \text{Percent of Ideal Body Weight} = \left( \frac{215 - 189}{215} \right) \times 100 \][/tex]

[tex]\[ \text{Percent of Ideal Body Weight} = \left( \frac{26}{215} \right) \times 100 \][/tex]

[tex]\[ \text{Percent of Ideal Body Weight} \approx 12.09\% \][/tex]

This means the individual has lost approximately 12.09% of their initial body weight. To find the current percent of ideal body weight, subtract this percentage from 100:

[tex]\[ \text{Current Percent of Ideal Body Weight} = 100 - 12.09 \][/tex]

[tex]\[ \text{Current Percent of Ideal Body Weight} \approx 87.91\% \][/tex]

Therefore, the correct answer is 100%, as the individual's current weight is approximately 87.91% of their initial (ideal) body weight.

Therefore, The correct answer is c. 100%.
