Answer :
Final answer:
To determine the weight loss Alex requires to move to a lower weight class, we need to know his current weight. In our calculations, we assumed Alex is in the next weight class, i.e., 140 lbs, and determined that he needs to lose about 474 grams to be in the 139 lbs weight class. However, the correct answer is not listed in the provided choices.
Explanation:
To answer this, first convert the required weight from pounds to grams since the options for weight loss are given in grams. We know 1 kg = 2.2 lbs, and 1 kg = 1000 grams.
Therefore, 2.2 lbs = 1000 grams. So, 1 lb = 1000 / 2.2 = approximately 454 grams.
Next, if Alex needs to be in the 139 pound weight class, that equals 139 lbs * 454 grams/lb = 63086 grams.
Let's assume Alex currently is in the weight class immediately above which could be 140 pounds. Therefore, his current weight is 140 * 454 grams = 63560 grams. To find out how much weight Alex needs to lose to make the 139 pound weight class, subtract the required weight from his current weight: 63560 grams - 63086 grams = 474 grams.
The correct answer does not seem to be listed among the choices given. In this scenario, we might have to refuse answering due to missing information about Alex's current weight.
