Do flowering plants have small roots or big roots?
A. Yes
B.No

The answer to your question is small roots

So to find the equations for this problem you will find that multiplying the rising points by what week they have been practicing will work in both equations, then you will also find that they will both add their current score and all of that will equal their now current score (in points). I chose the following variables:
w=weeks
p= number of points
Here are their equations:
Khan's: 750+8w=p
Jorman's: 650+30w=p

Hope this helps!
