5. Notice three different periods of relatively consistent ticket price change: The years 1980 – 1988, 1989 – 1993 and 1994 – 2010. Can you find a typical rate of change in the price of a ticket for each of these time periods? Restating that question, on
average, by how much did the price of a ticket increase by each year during each of these time periods?

6. Predict the cost of a ticket in the years 2019 – 2025 using the data from this chart. Give your predictions for each year below.

How did you determine how much a ticket would cost each year? (what method did you use)

7. Find a line of best fit to represent the data? Let y = ticket price and x = the number of years since 1980 (1980 is year zero, 1981

is year one). Approximate a line to represent the data – you must provide the points and work you used to calculate an equation

that models your line of best fit
