Explanation:

Step1: Locate 35 - year - old females on the graph

Find the point on the red line (representing females) corresponding to age 35.

Step2: Determine the percent body fat value

Read the percent body fat value on the y - axis at that point. From the graph, for 35 - year - old females, the percent body fat is 32%.

Step3: Locate the maximum for females on the graph

Scan the red line to find its highest point.

Step4: Determine the age at the maximum

Read the age value on the x - axis at the highest point of the red line. The percent body fat in females reaches a maximum at 55 years old.

Step5: Determine the percent body fat at 55 years old for females

Read the percent body fat value on the y - axis at the age of 55 for the red line. It is 36%.
