B) write an equation (linear function) that models the situation. let x represent the
number of times jabar goes to the pool. let y represent the total amount of money
jabar spends by going to the pool x times.

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.

The answer is 49/16 or 3 1/16
