The number in parentheses at the end of an exercise refers to the learning objective listed at the beginning of the chapter.

Suppose that billingAmount is a double variable, which denotes the amount you need to pay to the department store. If you pay the full amount, you get $10.00 or 1% of the billingAmount, whichever is smaller, as a credit on your next bill; if you pay at least 50% of the billingAmount, the penalty is 5% of the balance; if you pay at least 20% of the billingAmount and less than 50% of the billingAmount, the penalty is 10% of the balance; otherwise, the penalty is 20% of the balance. Design an algorithm that prompts the user to enter the billing amount and the desired payment. The algorithm then calculates and outputs the credit or the remaining balance. If the amount is not paid in full, the algorithm should also output the penalty amount. (3)
