At a local fitness center members pay a $10 membership fee and $4 for each aerobics class. Non members pay $5 for each aerobics class. For what numbers of aerobics classes will the cost for members and non members be the same?

In all honesty, there really is no “work” per say to show. mainly it’s just using the process of elimination. the question is asking which domain(s) would be the most appropriate for the function c(n). n is the number of observed vehicles so right away, 1, 2, and 3 can be eliminated.why? 1, 2 start in the negatives and therefore it is impossible to observe negative cars. so, #4 would be the best answer to the given problem.
