An online software store just had a sale. The percentage discount on their items was given based on the following chart: Price Discount $0-$15 5% >$15 and $35 The end-user wants to figure out how much their total will be based on the total purchase price. Assume 8% sales tax is added to the total after the discount is applied, for example: Purchase price = $80 Discount = .20*(%80) = $16 Total after discount = $64 Tax = .08*($64) = $5.12 Total after tax = $69.12 Write a GUI program that has the three options (radio buttons) for a percent discount based on the price of an item, an input entry box for the price, an output label for: the total after tax, the tax, and the discount, and two buttons: Total and Exit. Once the user enters the price into the entry box and clicks the Total button, the output labels will appropriately display the necessary amounts. If the price doesn't satisfy the range identified for the discount some error message should be displayed notifying the user.
