I need help with my Java homework!

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 charges.

Modify the program so it calculates and displays the amount of money Packaage A customers would save if they purchased Packages B or C, and the amount of money Package B customers would save if they purchased Package C. If there would be no savings, no message should be printed.

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 acess is provided.

hope this helps

THANKS!

but how would I do the second part?

"Modify the program so it calculates and displays the amount of money Packaage A customers would save if they purchased Packages B or C, and the amount of money Package B customers would save if they purchased Package C. If there would be no savings, no message should be printed."

thanks,

Matt
