(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

The profit, P, of a video company, in thousands of dollars is given by P=-5x^2+550x-5000, where x is the amount spent on advertising in thousands of dollars.

a) Determine the amount spent on advertising that will result in a profit of $0.

2. Relevant equations

P=-5x^2+550x-5000

3. The attempt at a solution

P=-5x^2+550x-5000

0=-5x(x-110)-5000

-5x=0 or x-110=0

x=0 or x=110

Therefor when the amount of $110 thousand is spent there will be a profit of $0.

This answer kind of confuses me but on the graph it appears to be accurate. Could someone please review this and tell me if I am incorrect and what I could do to correct it? Thank you in advance.
