b. $37.50
Step-by-step explanation:

. We already know the amount they each paid, as it is given as $9.50. Both expressions represent the same thing, do we can set them equal to each other:

Now, we can solve.
First, we can multiply by 5 on both sides to get:

x = 37.5
This means the bill before the tip was $37.50
