Answer 1

To calculate the total amount of the bill in the WPF app, you need to create ComboBoxes for product categories, add prices to the bill based on the selected items, calculate the subtotal, tax, and total amount, and provide a Clear Bill button. Furthermore, you can include your student name and company logo in the status bar and open your company's website when the logo is clicked.

Step-by-step explanation:

To calculate the total amount of the bill in the WPF app, you can follow these steps:

1. Create four ComboBoxes and populate them with the categories of products offered by the store.
2. When the user selects an item from any of the ComboBoxes, add the price of that item to the bill.
3. Calculate the subtotal by summing up the prices of all selected items.
4. Calculate the sales tax by multiplying the subtotal by the tax rate (18%).
5. Add the sales tax to the subtotal to get the total amount.
6. You can provide a Clear Bill button that resets the subtotal, tax, and total fields to $0.00.
7. To add your student name and company logo to the status bar, you can modify the WPF app's layout and include the necessary code.
8. To open your company's website in Internet Explorer when the logo is clicked, you can use the appropriate event handler to launch the default web browser and navigate to your website.
