JAVA PROGRAM

Chapter 5. PC #2. Retail Price Calculator (page 312)

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
