members pay ​$6 membership fee and ​$2 for each aerobics class. Nonmembers pay ​$4 for each aerobics class. For what number of aerobics classes will the cost for members and nonmembers be the​ same?

Answer 1

6 + 2C = 4C

2C = 6

C = 3 classes will make the cost the same for members and non members

for more than 3 classes, it's cheaper to be a member

for 1 or 2 classes, it's cheaper to be a non member
