The answer is: [D]: "p(x) = 5x – 20" .
_____________________________________
Explanation:
_____________________________________
"What is p(x) ? "
_____________________________________
"p(x) = r(x) – c(x)"
_____________________________________
r(x) = 11x ;

c(x) = 6x + 20 ;

p(x) = 11x – (6x + 20)

= 11x – 1(6x + 20)

= 11x – (1*6x) + (-1* 20)

= 11x – 6x + (-20)

= 11x – 6x – 20

= 5x – 20 ;

p(x) = 5x – 20 ; which is: "Answer choice: [D]" .
