Two Column Method - Black Friday

  1. Hey Jan,

    Your two column problem-solving is so 'neat'.
    But good job for sure (we have the same solution)!
    Anyways, it's interesting to see that I have also seen the pattern that you have observed in this problem. Hence, your solution method uses a similar idea to mine yet it is still not quite the same.

  2. Wow, you actually typed it all up! It is very neat. I noticed you considered the leap year and 12 month periods other than January to December. Good job Jan!
