Welcome to the Ranch
I am afraid your question suggests to me that you are guessing. You mustn't guess. Well, you can. If you make 1000000 guesses, make sure they are all different, and there is a good chance one will be correct. Or you can work it out and get it right first time
SB suggests your first code works, but I am afraid that doesn't get you very far. You have not written object‑oriented code.
You should have a Package class with a price field. You should instantiate three Package objects and get them to work out the cost of each. You should remove all that code from the
main method.
I suggest you need to turn your computer off and work out with pencil and paper how you intend to calculate the charges. I see there is a formula with monthly fee, base hours and additional hours. One of the packages does not seem to have base hours, but you can easily put that in the same formula by using 0 for base hours. Or maybe 0 for charge per additional hour.
