Create an application that contains a method that computes the final price for a sales transaction and returns that value to a calling method. The sale() method requires three arguments: product price, salesperson commission rate, and customer discount rate. A product’s final price is the original price plus the commission amount minus the discount amount; the customer discount is taken as a percentage of the total price after the salesperson commission has been added to the original price. Write a main() method that prompts the user for the price of an item, the salesperson’s commission expressed as a percentage, and the customer discount expressed as a percentage. Save the application as Calculator. java.
