How did you get all the variables?

For those who don't understand how, why, or what matrices and matrix determinants are used for.

Since it seems that there aren't many math enthusiasts (unfortunately), here's one of the spreadsheets I use (it's hard to make the first one, but then in Excel, it's easy to adjust by changing the assets).

You can check out the printout of the table (you can search all over the internet, I don't use copy and paste, it's mine).

Just compare it with the graph and see if you didn't predict the trend correctly 85% of the time.
