Answer

Brief Explanations:

The problem is about interpreting the variable in a linear function model. In the equation (f(x)=0.5 + 2x), since Sean increases his run by 2 miles per month, (x) should represent the time - related quantity (months) over which the increase occurs. The 0.5 is the initial distance (one - half mile), and 2x represents the additional distance added over (x) months.

Answer:

B. months he runs.
