Im very new to programming in general. I am taking JAVA 1 in college now. And my current assignment is to write a program that calculates a users total for a Internet Service Provider, depending on what type of package they choose. On package A, they are supposed to be billed $2 for every hours after 10 hours of internet use. on Package B, they are supposed to be billed $1 for every hours after 20 hours of internet use. I am having trouble on how to add that $2 for every hour over 10 hours of internet use in my code. Can someone help me?

Here is what I have so far. You will see the packages available in the code.
