Scratch Budget with Lists

Your mission to create a Python program using lists that does the following:
-asks the user their salary
-asks them to add the name of an expense and the dollar amount of that expense
-subtracts the expense from salary
-repeats the loop until salary equals zero

When salary equals zero, tell the user what their average cost.  Like “Rod, your average cost is: $500.

Hints:
1. make two lists: one called budgetItems and one called budgetCost
2. look at your other list programs to figure out how to repeat the loops.
