Write a program that computes that amount of money acomputer club will receive from proceeds of their Magwinya café sales project. The Magwinya are sold in cases that contain a dozen in each case. Allow the user to enter the number of cases sold and the sale price per gwinya. Each case contains 12 mawginya; each case is purchased at R15.00 per case from a local vendor. The computer club is required to give the SRC 10% of their earnings. Display their proceeds formatted with currency. Display instructions to the user about the application. Display all inputs and calculated values. Write appropriate methods for your solution.

Write a program that can be used to determine the tip amount that should be added to a restaurant charge. Allow the user to input the total, before taxes and the tip percentage (15% or 201%). Produce output showing the calculated values including the total amount due for both the 15% and the 201% tips.

Write a program that includes an Employee class that can be used to calculate and print the take home pay for a commissioned sales employee. All Employee receives 7% of the total sales. Income tax rate is 18%. Retirement contribution is 10%. Social security tax is 6%. Write instance methods to calculate the commission, income tax and social security tax withholding amounts as well as the amount withheld for retirement. Use appropriate constants. Design an object oriented solution and write constructors. Include at least one mutator and one accessor method; provide properties for the other instance variables. Create a second class to test your design. Allow the user to enter values for the name of the employee and the sales amount for the week in the second class.

Create a windows application that contains two TextBox objects and two Button objects. One of the TextBox objects and one of the buttons are initially invisible. The first textbox should be used to input a password. The textbox should be masked to some character of your choice so that the characters entered by the user are not seen on the screen. When the user clicks the first button, the second TextBox object and button object should be displayed with a prompt asking the user to reenter his or her password. Now the user clicks the second button, have the application compare the values entered to make sure they are the same. Display an appropriate message indicating whether they are the same.

The Information Systems Department is selling T-shirts. Create an attractive user interface that allows users to select sizes (S, M, L, XL) and quantity. Choose the most appropriate controls. Remember, the fewer keystrokes required of the user the better. Display the selections made by the user with the Process menu option. Include an option to exit the application. Include two more sizes, XSmall and XXLarge. Add statements that process the order by calculating the total cost. Each shirt is $16 except the XSmall and XXLarge; their speciality prices are $20 each Display the total cost of then selection. Include a help option that displays instructions. You can enhance your solution by allowing users to purchase different sizes on the same order.

The following program prompts the user to enter the size of the fertilizer bag, in pounds, the cost, and the area, in square feet, that can be covered by the bag. The program should output the desired result. However, the program contains logic errors
