Question 551225: The profit P, of a video company (in thousands of dollars) is given by P(x) = -5x^2+550x-5000. X is the amount spend on advertising in thousands of dollars.
Determine the amount spent on advertising that will result in a profit of $0. Describe the relationship and the graph of P(x)
I think you need to factor P(x)=5x^2+50x(11-x)- 50x(100-x) I really do not know how to factor that Answer by nerdybill(7384) (Show Source):
You can put this solution on YOUR website! Starting with:
P(x) = -5x^2+550x-5000
since profit is zero, replace P(x) with a zero:
0 = -5x^2+550x-5000
multiply both sides by -1:
0 = 5x^2-550x+5000
divide both sides by 5:
0 = x^2-110x+1000
factoring:
0 = (x-10)(x-100)
x = {10,100}
two solutions:
$10 and $100
