First off -- nice first draft of this challenge, Cart! I ran it locally with success ... however, when I passed non-integer inputs, the script failed.

Beginning in line 12 of the cake sale script, you are casting inputs as integers -- not so different than your Number_Guesser. If you recall, in your Number_Guesser script, you had some basic checks to make sure inputs were actually numbers. I would just hack that basic structure and apply here.

Hey J.

I discovered some repos that may be of help to you

Lots of algorithms implemented
https://github.com/TheAlgorithms/Python

set up AWS development environment locally to learn the stack while avoiding paying the piper (i'll be deploying this on carme sometime soon-ish and could give you access)
https://github.com/localstack/localstack

other neatness:
algorithmic trading: https://www.zipline.io / https://github.com/quantopian/zipline
secure remote-computer communication: https://github.com/fabric/fabric

Added a new Cale Sale Challenge!!

only one line printed per loop, so just rethink where your newlines are; you dont need to pad printouts with empty lines, this just makes for extraneous scrolling.

you leveraged the least common multiple by checking that first. good.

but now, if I asked you to switch to 7 and 2 instead of 5 and 3, you have to change code on three different lines.

do we really need three if statements?
