Answer:
Now plot those points in graph and find intersection hope it helps you.......
18 would have to be the mean because of the average
If r(x)= 11x, and c(x)=6x +20, then just put that into the equation.
So instead of p(x) = r(x) - c(x)
I would be p(x) = 11x - 6x + 20
Now solve.
p(x) = 5x + 20 is your final answer, so A.
