Internet Service provider Part 1

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 customers 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.
