Like we did in the labs, the goal of this assignment will be to take fully
concrete classes, and modify them to use either an interface or
abstract class
There are many TODOs for you to complete
Do NOT delete the TODO comments. I use them when grading, and will
deduct points if you delete them.
You can assume that the user enters valid menu choices
You can assume the user enters positive decimal values as the payments
