If an athlete weighs 151 lb and has 15.0% body fat by weight, how many pounds of fat does the athlete's body contain?

A. 22.7 lb
B. 22.65 lb
C. 10.1 lb
D. 10.06 lb

Answer :

Sure, let's solve this step-by-step:

1. Determine the total weight of the athlete:
The weight of the athlete is given as:
[tex]\[ 151 \text{ lb} \][/tex]

2. Convert the body fat percentage to a decimal:
The body fat percentage is given as:
[tex]\[ 15.0\% \][/tex]
To use this in calculations, we convert it to its decimal form by dividing by 100:
[tex]\[ 15.0\% \div 100 = 0.15 \][/tex]

3. Calculate the pounds of body fat:
To find out how many pounds of fat are in the athlete's body, we multiply their total weight by the body fat percentage (in decimal form):
[tex]\[ \text{body fat (lb)} = \text{total weight (lb)} \times \text{body fat percentage (decimal)} \][/tex]
[tex]\[ \text{body fat (lb)} = 151 \times 0.15 \][/tex]
[tex]\[ \text{body fat (lb)} = 22.65 \][/tex]

Therefore, the athlete's body contains [tex]\( 22.65 \)[/tex] pounds of fat.

So the correct answer is:
[tex]\[ \boxed{22.65 \text{ lb}} \][/tex]
