Question

with aging, body fat increases and muscle mass declines. the graph to the right shows the percent body fat in a group of adult women and men as they age from 25 to 75 years. age is represented along the x - axis, and percent body fat is represented along the y - axis. for what age does the percent body fat in men reach a maximum? what is the percent body fat for that age? the percent body fat in men reaches a maximum at the age of years.

Explanation:

Step1: Locate the men's curve

Identify the curve representing percent body - fat in men on the graph.

Step2: Find the peak

Locate the highest point on the men's curve. The x - value at this point is the age when percent body - fat reaches a maximum, and the y - value is the percent body - fat at that age.
From the graph, the men's curve (usually the upper curve) reaches its maximum at an x - value of 50 years. The corresponding y - value (percent body - fat) at this point is 25.

Answer:

The percent body fat in men reaches a maximum at the age of 50 years. The percent body fat for that age is 25.
