Hey user☺☺
The graph will have no solution.
Hope it works
Cid Sam is a way to remember
C -control S - SAME (keep the same)
I -independent A- alter
D-depend M- measure
independent- number of downloads
Dependant - money spent
Its basically just subtracting from one another
for example, 6-6 is 6
or -4-3= 7
I've answered this before, but only partially. I'm not sure about the second part, but I think the first one is 10
