THIS IS FOR 21 POINTS!!!
Marcus is a member of a theater club. He pays a monthly fee and his movie tickets are then $5 for an unlimited number of movies that month. Look at the graph to answer the question. Find the monthly fee. I can't put the graph on here, so I'm just going to list the points.
1, 12.50; 2, 17.50; 3, 22.50; 4, 27.50
A. 7.50
B. 8.50
C. 10.50
D. 35.00
The graph tells us that if he watches only one movie, it costs him $12.5. That includes the monthly fee + $5 for the film. The monthly fee is thus 12.5-5=7.5$
