Create an application, using the following names for the solution and project, respectively: Jerome Solution and Jerome Project. Save the application in the VB2015\ Chap04 folder. Create the interface shown in Figure 4-58. The Calculate button’s Click event procedure should add the item price to the total of the prices already entered; this amount represents the subtotal owed by the customer. The procedure should display the subtotal on the form. It also should display a 5% sales tax, the shipping charge, and the grand total owed by the customer. The grand total is calculated by adding together the subtotal, the 5% sales tax, and a $6.50 shipping charge. For example, if the user enters 15.75 as the price and then clicks the Calculate button, the button’s Click event procedure should display 15.75 as the subtotal, 0.79 as the sales tax, 6.50 as the shipping charge, and 23.04 as the total due. If the user subsequently enters 10 as the price and then clicks the Calculate button, the button’s Click event procedure should display 25.75 as the subtotal, 1.29 as the sales tax, 6.50 as the shipping charge, and 33.54 as the total due. However, when the subtotal is at least $100, the shipping charge is 0.00. Test the application appropriately.
