Three kinds оf tickets аre аvаilable fоr a cоncert: "up close", "in the middle", and "nosebleed". "Up close" tickets cost $20 more than "in the middle" tickets. "In the middle" tickets cost $35 more than "nosebleed" tickets. Twice the cost of an "up close" ticket is $30 more than 10 times the cost of a "nosebleed" ticket. (a) Write a system of equations that models this application, where x is the price of "up close" tickets, y is the price of "in the middle" tickets, and z is the price of "nosebleed" tickets. (b) Find the price of each kind of ticket by solving the system of equations produced in step a. You will only receive credit if you use solving systems techniques on the equations set up in a, and show your work. NO CREDIT WILL BE PROVIDED FOR ANSWERS OBTAINED THROUGH OTHER MEANS (such as 'guessing' at the prices).
