    package lesson2.skowronek;

    import java.util.Scanner; //Needed for the scanner class

    public class Ex3_13 {

    public static void main(String[] args) {
    String input; //To hold users input.

    char selectPackage; //To hold Internet Package

    double hourUsage, totalCharges, addCharges; //other variables

    //Create a Scanner object for keyboard input.
    Scanner keyboard = new Scanner(System.in);

    //Prompt the user to select a Internet Package.

    System.out.print("Please select the package that you have purchase.");
    input = keyboard.nextLine();
    selectPackage = input.charAt(0);


    System.out.print("Please select the amount of hours used.");

    input = keyboard.nextLine();
    hourUsage = Double.parseDouble(input);

    //Display pricing for selected package...

    switch (selectPackage)
    {
    case 'a':
    case 'A':
    if (hourUsage > 10)
    {
    addCharges = hourUsage - 10;
    totalCharges = (addCharges * 2.0) + 9.95;
    System.out.println("You have used " + hourUsage + " hours and your total is $" + totalCharges + " per month. ");
    }
    else
    {
    System.out.println("Your total is $9.95 per month.");

    }
    break;

    case 'b':
    case 'B':
    if (hourUsage > 20 )
    {
    addCharges = hourUsage - 20;
    totalCharges = (addCharges * 1.0) + 13.95;
    System.out.println("You have used " + hourUsage + " and your total is $" + totalCharges + " per month.");
    }
    else
    {
    System.out.println("Your total is $13.95 per month.");

    }
    break;

    case 'c':
    case 'C':
    System.out.println("Your total is $19.95 per month.");
    break;
    default:
    System.out.println("Invalid Choice.");
    }

    }


    }

    Go ahead and try this out, I had to due the same problem for my class and it worked nicely. The suggestion from one of your peers on this site to use an if statement was a good one. If you look in the book, generally the code assignments require that you use what was reflected in the chapter. As you pick up more concepts, tried to incorporate material covered in previous chapters when necessary. If you don't use it, you will lose it.
