Answer:
Step-by-step explanation:
Step one:
given data
Revenue
[tex]R(x) = 35x[/tex]
Total cost
[tex]C(x) =20x +500[/tex]
profit
[tex]P(x) =R(x) - C(x)[/tex]
Required
the value of  P(x)
Step two:
substituting we have
[tex]P(x) =35x- (20x+500)\\P(x)=35x-20x-500\\\\P(x)=15x-500[/tex]
Option C is correct
c) 15x-500
