Step-by-step explanation:

Let as assume we need to find the change in the t-value over the first five weeks; that is, from t = 0 to t = 5.

The data in the following table represents your weight, w, as a function of time, t, over an eight-week period.

From the given table it is clear that w=150 at t=0 and w=137 at t=5.

The change in the t-value over the first five weeks; that is, from t = 0 to t = 5 is

The change in the w-value over the first five weeks; that is, from t = 0 to t = 5 is

Therefore, the change in the t-value is 5.
