Answer:
The expression that represents the profit is [tex]p(x) =3x-180[/tex]
Step-by-step explanation:
The Profit function P(x) is the difference between the Revenue function R(x) and the Cost function C(x)
[tex]P(x) = R(x)-C(x)[/tex]
Finding the profit function.
For this exercise the revenue is given by
[tex]R(x) = 5x^2+2x-80[/tex]
And the cost function is modeled by
[tex]C(x) = 5x^2-x+100[/tex]
Thus the profit function is
[tex]P(x) = 5x^2+2x-80- (5x^2-x+100)[/tex]
Distributing the negative sign.
[tex]P(x) = 5x^2+2x-80- 5x^2+x-100[/tex]
Combining like terms to finally get the simplified profit function
[tex]\boxed{P(x) = 3x-180}[/tex]
