Final answer:
Luis is a healthy 23-year-old male who isn't an athlete. Luis is 6' 3" and weighs 235 pounds. Based on this information, his RDA for protein is about 65 grams.Thus the correct option is b. 65 grams.
Explanation:
Based on Luis's information, his Recommended Dietary Allowance (RDA) for protein is about 65 grams. This calculation is determined by multiplying his weight in kilograms by the recommended protein intake for adults, which is approximately 0.8 grams per kilogram of body weight.
To calculate Luis's weight in kilograms, we need to convert his weight from pounds to kilograms. Since 1 pound is approximately 0.4536 kilograms, Luis's weight of 235 pounds converts to approximately 106.59 kilograms.
Next, we multiply Luis's weight in kilograms (106.59) by the recommended protein intake (0.8 grams per kilogram) to find his RDA for protein. The result is 85.272 grams. However, since Luis is not an athlete, the recommended protein intake is slightly lower. Thus, we estimate his RDA for protein to be around 65 grams, considering his age, height, and lifestyle factors.
In summary, based on Luis's demographic information and the recommended protein intake guidelines, his RDA for protein is approximately 65 grams per day. This amount ensures that he meets his body's protein needs for maintaining muscle mass, repairing tissues, and supporting overall health, considering his height, weight, and activity level.
Thus the correct option is b. 65 grams.
