What's wrong with my codes? Please help!

Question

*Questions are #13 and #14. These should be combined.
Can you please tell me why the following is not answering the questions #13 and #14?
Thank you!!

          An Internet service provider has three different subscription
          packages for its customers:
          Package A:          For $9.95 per month 10 hours of access are provided.
                              Additional hours are $2.00 per hour.
          Package B:          For $13.95 per month 20 hours of access are provided.
                              Additional hours are $1.00 per hour.
          Package C:          For $19.95 per month unlimited access is provided.
          Write a program that calculates a customer's monthly bill. It should
          ask the user to enter the letter of the package the customer has
          purchased (A, B, or C) and the number of hours that were used. It should
          then display the total charges.
     #14:
          Modify the program you wrote for Programming Challenge 13 so it also
          calculates and displays the amount of money Package A customers
          would save if they purchased Package B or C, and the amount of
          money Package B customers would save if they purchased Package C.
          If three would be no savings, no message should be printed.
