Modify the answer to Exercise 1 as follows. Jerry will be charging the total bill, including the tip, to his credit card. Modify the solution so that, in addition to calculating and displaying the appropriate tip, it also calculates and displays the amount charged to Jerry's credit card. Desk-check the algorithm using $50 as the total bill, $5 as the liquor charge, and 20% as the tip percentage. Then desk-check it using $15 as the total bill, $0 as the liquor charge, and 15% as the tip percentage
