They noticed that one year later, in 2001, the cost of an adult one-day ticket to Disneyland was $43, while three years later in 2003, the cost was $47. a. What is the independent variable (a) in this information? Select an answer b. What is the dependent variable (y) in this information? Select an answer c. Find the rate of change for this data. What does it mean in this situation? The rate of change is Select an answer which represents the change (increase) in Select an answer per d. Find an equation for the ticket price T' based on the number of years after 2000. This means the data as ordered pairs looks like: (1, 43), (3, 47) T = e. Use your equation to predict the ticket price in 2006. For 2006, since it is years after 2000, we use x = and we get: T= dollars
