(b*amount of money per hour) + (s*amount of money per hour).
Step-by-step explanation:

We have been given that a 208-yard-long road is divided into 16 parts of equal length.
Let us find length of each part.


Length of each part will be 13 yards.
We are told that Mr. Ward paints a 4-yard-long strip in each part.
Now we will subtract length of painted strip from length of each equal part to find length of unpainted strip of each part of the road.
Therefore, length of each unpainted strip will be 9 yards.
