Final answer:
To calculate Mr. J's adjusted body weight, we need to consider his ideal body weight (IBW) and make adjustments based on certain factors. The adjusted body weight is calculated as 0.4 times the difference between the actual weight and the ideal body weight, then added to the ideal body weight. We cannot determine the exact value of the adjusted body weight without the actual weight.
Step-by-step explanation:
To calculate Mr. J's adjusted body weight, we need to consider his ideal body weight (IBW) and make adjustments based on certain factors. The adjusted body weight is calculated as 0.4 times the difference between the actual weight and the ideal body weight, then added to the ideal body weight. So, the formula for calculating the adjusted body weight is:
Adjusted Body Weight = IBW + (0.4 × (Actual Weight - IBW))
Let's calculate Mr. J's adjusted body weight using his ideal body weight of 84.5kg:
Adjusted Body Weight = 84.5 + (0.4 × (Actual Weight - 84.5))
Since we don't have the actual weight, we cannot determine the exact value of the adjusted body weight. Therefore, none of the options provided (a) 90.5kg, (b) 86.5kg, (c) 84.5kg, (d) 80.5kg can be confirmed as the correct answer. We would need the actual weight value to calculate the adjusted body weight.
