Final answer:
Available weight gain is usually calculated by subtracting post-treatment weight from pre-treatment weight; however, given the values (pre-treatment weight of 205 pounds and post-treatment weight of 295 pounds), the result is negative, which indicates a possible error.
Step-by-step explanation:
Available weight gain is described as the pre-treatment weight minus the post-treatment weight. Based on the information provided, the pre-treatment weight is 205 pounds and the post-treatment weight is 295 pounds.
Using these values, the available weight gain can be calculated by subtracting the post-treatment weight from the pre-treatment weight: 205 pounds (pre-treatment) - 295 pounds (post-treatment) = -90 pounds. However, this results in a negative number, which suggests that there was not a weight gain but instead a weight loss or a misunderstanding in the context of 'available weight gain.'
Typically, available weight gain would be a positive value if the subject actually gained weight. Therefore, please ensure that the terms 'pre-treatment' and 'post-treatment' weights are correctly used as this calculation indicates an unexpected result in the context of weight gain.
