Angel bought 15 tickets to a movie, where adult tickets cost $6.00 and senior citizen
tickets cost $4.00. She spent a total of $76. Which system of equations will determine
the number of adult tickets, a, and the number of senior citizen tickets, s, Angel
purchased?
Based on the equation you chose, solve to find out how many of each kind of ticket
Angel purchased.

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.
