Answer:

Explanation:

To calculate the client's approximate weight when he reaches his goal of 15% body fat, we need to determine his current lean body mass (LBM) and fat mass.

Given:

Current weight: 180 lbs

Current body fat percentage: 20%

Goal body fat percentage: 15%

Calculate the current fat mass:

Fat mass = Current weight * (Current body fat percentage / 100)

Fat mass = 180 lbs * (20 / 100) = 36 lbs

Calculate the current lean body mass:

Lean body mass = Current weight - Fat mass

Lean body mass = 180 lbs - 36 lbs = 144 lbs

Calculate the target fat mass:

Target fat mass = Current weight * (Goal body fat percentage / 100)

Target fat mass = 180 lbs * (15 / 100) = 27 lbs

Calculate the target weight:

Target weight = Target fat mass + Lean body mass

Target weight = 27 lbs + 144 lbs = 171 lbs

Therefore, the client's approximate weight when he reaches his goal of 15% body fat, assuming his lean body mass remains constant, would be approximately 171 lbs (option C).
