7. 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 customer's 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. 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.

Restrictions:
1) Use only Sub routines for this assignment
2) Your calculate button cost MUST look like this:
Private Sub btnCalc_Click(sender As Object, e As EventArgs) Handles btnCalc.Click
calcSub()
calcTax()
calcTotal()
