Functionality of the program: • 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. Example of the program output. Form1 X Wholesale cost: Markup percentage (2): 50 Retail price: $7.50 Calculate 1. Create a method called Calculate Retail that has 2 parameters and will return the Retail Price; a. Parameter 1 is a double pCost b. Parameter 2 is a double pPercent c. The return datatype is a double d. The method will use the formula above for the calculation of the Retail Price and it will return the value
