Answer:
P(x) = 42x-250.
Step-by-step explanation:
We have just to write P(x), which is R(x) - C(x), so:
P(x) = R(x) - C(x) = (50x)-(8x + 250)
The minus sign before the parenthesis means that everything inside the parentesis must be turned negative, so we have:
P(x) = 50x-8x-250.
Finally, we can add or substract same x-dependant terms, which is, only constants can be added or substracted between them, only terms with x can be added or substracted between them, only terms with [tex]x^2[/tex] can be added or substracted between them, and so on, so we will have:
P(x) = 50x-8x-250=42x-250.
