Write a program that asks the user to enter an item’s wholesale cost and its markup percentage. It should then display the item’s retail price. For example: • If an item’s wholesale cost is 5.00 and its markup percentage is 100 percent, then the item’s retail price is 10.00. • If an item’s wholesale cost is 5.00 and its markup percentage is 50 percent, then the item’s retail price is 7.50. The program should have a method named calculateRetail that receives the wholesale cost and the markup percentage as arguments, and returns the retail price of the item. Class name: RetailPriceCalculator Here is a working code but please fix it so it will in Hypergrade which as all the test casses. I DO NOT NEED THANK YOU IN THE PROGRAM. IT HAS TO PASS ALL THE TEST CASSES PLEASE.
