Question

At a local fitness​ center, members pay aa ​$12 membership fee and ​$3 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? I'm having trouble trying to figure this out.

Answer 1

For x sessions,
members pay 12 + 3x
non-mebers pay 4x
So, what do you think?

Or, consider that members save $1 each session, so how long will it take to save the $12 fee?

Answer 2

actually the answer was 12 thank you oobleck
