Ok, we have two expressions:
$30x + 1500$
$19x + 9000$
The first thing to note is, the first expression is $100\%$ and the second expression is $0\%$.
The second thing is to note in all of this is, $x$ is infinite in these expressions.
Ok, my main question is where would $23x + 15590$ go in the range as a percent? and how do you prove this? I don't know how but I'll accept any answer that makes sense. Bearing in mind $x$ is infinite, how?
Thank you though, I look forward to your answers.
EDIT: Hello guys, I apologize if that didn't make any sense. I meant in terms of this: link
