Add a menu item that is "Increase miles" where you should be able to select a car by entering its location in the register and then can increase the number of miles it has traveled. So to increase the fiat's miles above, enter 3.

Edit: this question is a following question to a previous one which was:

In question number one we should Add the function that prints all cars in the register in our car register program. The printout should look as follows:
1. Car: Volvo, Year model: 2011, Mil: 3000
2. Car: Saab, Year model: 2000, Mil: 5000
Car: Fiat, Model year: 1999, Mil: 40000

Then in a separate question we should Change the program so that it starts with a menu according to
below. Depending on what you choose, the correct function is called. Then the user gets another chance to choose until he chooses to quit.

• register cars

• Print all cars
• Exit

Buckeye Creek Amusement Park is open from the beginning of May to the end of October. Buckeye Creek relies heavily on the sale of season passes. The sale of season passes brings in significant revenue prior to the park opening each season, and season pass holders contribute a substantial portion of the food, beverage, and novelty sales in the park. Greg Ross, director of marketing at Buckeye Creek, has been asked to develop a targeted marketing campaign to increase season pass sales. Greg has data for last season that show the number of season pass holders for each zip code within 50 miles of Buckeye Creek. he has also obtained the total population of each zip code from the U.S. Census bureau website. Greg thinks it may be possible to use regression analysis to predict the number of season pass holders in a zip code given the total population of a zip code. If this is possible, he could then conduct a direct mail campaign that would target zip codes that have fewer than the expected number of season pass holders.

1. Did the estimated regression equation provide a good fit?

2. Use residual analysis to determine whether the assumed regression model is appropriate.

3. Discuss if/how the estimated regression equation should be used to guide the marketing campaign.

4. What other data might be useful to predict the number of season pass holders in a zip code?
