A. 72 pounds
B. 75 pounds
C. 76 pounds
D. 80 pounds



Answer :

To determine how much of a 125-pound person's body weight is composed of water, we need to calculate 60% of their total weight.

Here is the step-by-step solution:

1. Identify the total body weight:
[tex]\[ \text{Total body weight} = 125 \text{ pounds} \][/tex]

2. Determine the percentage of the body weight that is water:
[tex]\[ \text{Percentage of water} = 60\% = 0.60 \][/tex]

3. Calculate the water weight:
Multiply the total body weight by the percentage of water:
[tex]\[ \text{Water weight} = 125 \text{ pounds} \times 0.60 \][/tex]

[tex]\[ \text{Water weight} = 75 \text{ pounds} \][/tex]

So, 60% of a 125-pound person’s body weight, which is composed of water, is exactly 75 pounds.

The correct answer is:
G. 75 pounds
