A retail company must file a monthly sales tax report listing the total sales for the month, and the amount of state and county sales tax collected. The state sales tax rate is 4% and the county sales tax rate is 2%. Create an application that allows the user to enter the total sales for the month. From this figure, the application should calculate and display the following:
- a. The amount of county sales tax
- b. The amount of state sales tax
- c. The total sales tax (county plus state)
In the application's code, represent the county tax rate (0.02) and the state tax rate (0.04) as named constants. Use the named constants in the mathematical statements. If the user fails to enter numeric values, display an appropriate error message and do not attempt to perform calculations. Use the following test data to determine whether the application is calculating properly:

- The Donut Shoppe sells four varieties of doughnuts: Glazed (1.05), Sugar (1.05), Chocolate (1.25), and Filled (1.50). It also sells regular coffee (1.50) and cappuccino (2.75). The store manager wants you to create an application that displays a customers subtotal, 6% sales tax, and total due. Create a Windows Forms application. Use the following names for the project and solution, respectively: Donut Project and Donut Solution. Save the application in the VB2017\Chap06 folder. Create the interface shown in Figure 6-57. When coding the application, use one independent Sub procedure to determine the subtotal, which is the total cost without the sales tax. Use a function to determine the sales tax. Use an event-handling Sub procedure to clear the output. Save the solution and then start and test the application.arrow_forwardFor each of the following exercises, you may choose to write a console-based or GUI application, or both. Write a program for The Carefree Resort named ResortPrices that prompts the user to enter the number of days for a resort stay. Then display the price per night and the total price. Nightly rates are $200 for one or two nights; $180 for three or four nights; $160 for five, six, or seven nights; and $145 for eight nights or more.arrow_forwardAccount numbers sometimes contain a check digit that is the result of a mathematical calculation. The inclusion of the digit in an account number helps ascertain whether the number is a valid one. Write an application named CheckDigit that asks a user to enter a four-digit account number and determines whether it is a valid number. The number is valid if the fourth digit is the remainder when the number represented by the first three digits of the four-digit number is divided by 7. For example, 7770 is valid, because 0 is the remainder when 777 is divided by 7. The next problems rely on the generation of a random number. You can create a random number that is at least mi n but less than max using the following statements: Random ranNumberCenerator = new Random(); int randomNumber; randomNumber = ranNumberGenerator .Next(min, max);arrow_forward
- The purpose of this exercise is to demonstrate the importance of testing an application thoroughly. Open the FixIt Solution.sln file contained in the VB2017\Chap04\FixIt Solution folder. The application displays a shipping charge that is based on the total price entered by the user, as shown in Figure 4-64. Start the application and then test it by clicking the Display shipping button. Notice that the Shipping charge box contains $13, which is not correct. Now, test the application using the following total prices: 100, 501, 1500, 500.75, 30, 1000.33, and 2000. Here too, notice that the application does not always display the correct shipping charge. (More specifically, the shipping charge for two of the seven total prices is incorrect.) Open the Code Editor window and correct the errors in the code. Save the solution and then start and test the application.arrow_forwardWhich statement terminates an application that contains only one form?

Quantity discounts are given according to the following table: Quantity Discount 10–19 20% 20–49 30% 50–99 40% 100 or more 50% Create an application that lets the user enter the number of packages purchased. The program should then display the amount of the discount (if any) and the total amount of the purchase after the discount.arrow_forward
