So I'm not quite understanding ps1b.py. The numbers don't add up right. It asks what the minimum monthly payment would be to pay off a balance within 12 months. Yet the first test case is wrong. The balance would be 1416, and if you paid 120 a month, and it took you 11 months. You'd only have paid 1320 back. Yet it says it has a negative balance.

Nevermind, I got it.  The wording in the question confused me.  It wants me to define a fixed monthly payment, and then figure out how many months it will take to pay it off, and what the remaining balance is.
