Question 1080721
-200x^2+8800x-94062=100x^2-4400x+47031, dividing both sides by -2
x=(1/200)*(4400+/- sqrt (19360000-400*47031); sqrt term is 547600=740
x=(1/200)(4400+/-740)=5140/200 or between 25 and 26; 3660/200 or between 18 and 19. There are two answers, showing that above a certain number, it will again become a loss.
