13.2 Lab 12 Credit Card Interest Rate Calculator Compute and output the penalty on an unpaid Credit Card balance. Assume that interest rate on unpaid balances is 1.5% per month. Ask the user for their credit card balance and monthly payment amount. Then output the new balance and the penalty amount to be added to the next month bill. For example if the user enters 1000 for the balance and 100 for the payment your output would be: The new credit card balance is: $900.00 The penalty to be added to your next month bill is: $13.50
