The equilibrium point x= a is the point where,
R(x) = C(x) at x=a or
So,solving for x, when 56x-2x^2=24x+101 or
2x^2+24x-56x+101 = 0, we get a.
2x^2-32x+101 = 0 or
2(x-8)^2-2*8^2+101 =0 or
2(x-8)^2 = 128-101 = 27 or
(x-8)^2 = 27/2 =13.5. or
x=8+sqrt13.5=11.6742 is the break even point where R(11.6742) and C(11.6742) equal and there is no profit and no loss.
