Bryan and Seth are both members of the same private social networking site. Bryan’s membership plan can be expressed with the function y = 9.50x + 22, where x is the number of months that he is a member and y is the total cost. Seth’s membership fees are shown in the graph.
If x represents the number of months that they are members of the social networking site, how much will Bryan and Seth each pay after 15 months of membership?
