Application Title: Trailer Rental Rates Application
Purpose: This application computes the cost to rent a truck, cargo van, or trailer for your mow. The application will calculate the total cost, including 8.5% state tax.
Program Procedures: The user can select the type of rental and the number of days.
Algorithms, Processing and Conditions:
1. The user first views a Windows form that displays a title, a picture of a moving truck, a ComboBox object requesting the type of rental (truck, $29.95 a day; cargo van, $19.95 a day; or trailer, $14.95 a day), and a TextBox object for the number of days.
2. After the information has been entered, a Sub procedure displays three labels: Subtotal Billing Amount for Your Rental, Taxes for Your Rental, and Final Total.
3. Pass the cost of the rental type and the number of days to a Sub procedure to calculate the rental subtotal. Do not display the amount in this procedure.
4. Another Function procedure should compute the 8.5% tax. Pass that value back to the calling method.
5. Pass the subtotal, tax, and final cost to a Sub procedure to display the results.
Notes and Restrictions: The input values should be validated in a separate procedure by a Try-Catch block.
Comments: The picture should be selected from pictures available on the Web.
