Open the VB2015\Chap03\Tax Solution\Tax Solution (Tax Solution.sln) file. The application displays a 5% sales tax on the purchase amount entered by the user. In the General Declarations section of the Code Editor window, enter your name, the current date, and the three Option statements. Use variables and the TryParse method to code the Calculate button. Declare a named constant for the sales tax rate, which will be 5%. Use the Format function to display the sales tax with a dollar sign and two decimal places. Save the solution and then start the application. Test the application without entering any data. Then test it using 100.57 as the purchase amount. Finally, test it using $67.98 for the purchase amount.
