Shawn Corder needs extra money quickly to help cover some unexpected school expenses. Mr. Corder has learned fortune-telling skills through his long friendship with Fred Molloy, who tells fortunes during the day at the city market. Mr. Molloy has agreed to let Mr. Corder use his booth to tell fortunes during the evening for a rent of $90 per night.

b. Is the cost of renting the fortune-telling booth fixed or variable relative to the number of customers?

c. Draw two graphs. On one, plot total booth rental cost for 5, 10, 15, 20, and 25 customers; on the other, plot booth rental cost per customer for 5, 10, 15, 20, or 25 customers.
