How much money in total would be paid by the 1st 150 student

113.25 because the middle ground of 1 - 150 students is 75 and then 1+150=151  2+149+151 but instead of doing that again and again just multiply the lowest number and the highest number by the middle ground

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.
