Profit is Revenue minus Cost, so:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ P(x)\ =\ R(x)\ -\ C(x)\ =\ \left(50x\ -\ 0.5x^2\right)\ -\ \left(4x\ +\ 10x^2\right)]


I&#39;ll lead the simplification and the graphing to you.


The profit function is a parabola that opens down.  The answer to part c is the value of the *[tex \LARGE x] coordinate of the vertex, and the  answer to d is the *[tex \LARGE y] coordinate of the vertex.

*[tex \LARGE e^{i\pi}\ +\ 1\ =\ 0]
My calculator said it, I believe it, that settles it
