No calculators may be used on this quiz. #1 (9 points): Due to recent demand, the Rutgers football team is considering raising ticket prices to pay for stadium upgrades. They are currently selling 24,500 tickets per game at \$15 per person (obviously a very simplified example). However, with every \$5 increase in ticket price, attendance will decrease by 3,500 so they need to find an optimal ticket price that will maximize the gross revenue per game. a) Find a linear function s(x) showing the number of tickets sold given a price x

Unformatted text preview: b) Using your function from part a, generate a function r(x) that shows the REVENUE generated for a given ticket price x (i.e. the price * # tickets sold) c) Finally, find the ticket price that maximizes revenue, using your function r(x) from part b. Be careful – you want the optimal ticket price, not number of tickets. d) According to your model, at what price would attendance THEORETICALLY go to zero? (obviously this model would break down at extreme values for x) #2 (6 points) A graph of f(x) is given to the left. Sketch the graph of ) 1 ( 2 ) (-⋅ = x f x g Assume that the entire function f(x) is shown in the given graph and that all bolded points are on integer values....

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
