Teresa will rent a car for the weekend. She can choose one of two plans. The first plan has an initial fee of $60 and costs an additional $0.40 per mile driven. The second plan has no initial fee but costs $0.90 per mile driven. How many miles would Teresa need to drive for the two plans to cost 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.

How many groups are there?
