Answer 1

The correct answer is:a. 137 - 150 = -13 lb;A change in weight is negative because the weight decreases.

Explanation:

The initial weight is 150 lb, and the weight at the end of the first five weeks is 137 lb.
When you subtract the initial weight from the weight at the end of the first five weeks, you get a negative value of -13 lb.

This negative value indicates that your weight has decreased by 13 lb over the first five weeks of the program.
The significance of the negative sign is that it represents a reduction in weight, which aligns with the statement that your weight decreases during each of the first five weeks of the program.
