Really simple once I remembered how to use the optimization tool. It seems that every time I run into it I have to learn how to use it all over again.
I forgot you could have lower and upper bounds in the objective function input! I also got slightly different values, as I solved for each arrangement. I ❤️ the optimization tool!
For the video solution I've removed a bit of the complexity by using the lower and upper bounds! https://www.youtube.com/watch?v=Wr-ZS_NdQ2k&list=PL18SpOXDj-KMUD4YwWC5vZaUsIa7drxNZ&index=18&t=0s
