You are planning to take a group of friends to the movies for your birthday. the local movie theater charges $12.99 per person. when you check the company's website, you find that they also offer a special group rate. the group rate is only $8.99 per person but also includes a $20 reservation fee in addition to the cost per person

The green line represents the group rate at the movie theater. The blue line represents the individual rate. The two lines intersect at the point (5, 64.95), which represents that the price for 5 people is the same for both the individual rate and the group rate. For fewer than 5 people, the individual admission rate line is below the group rate line. The maximum number of people who can attend the party and have the individual admission rate to be a better deal is 4 people. 

Agreed i also had the same answer

This does not make sense
