You can put this solution on YOUR website! The cost function for a certain company is C = 40x + 800 and the revenue is given by R = 100x − 0.5x^2. Recall that profit is revenue minus cost. Set up a quadratic equation and find two values of x (production level) that will create a profit of $800.
------
Profit:: P(x) = 100x-0.5x^2 - (40x+800)
P(x) = -5x^2 +60x - 800
-----
Solve for "x"::
-5x^2+60x - 800 = 800
-5x^2 + 60x - 1600 = 0
Note:: This quadratic has no Real Number solutions.
