    Correct option is:

    D) p (x) = 5x-12

    Step-by-step explanation:

    r (x) = 8x

    c (x) = 3x+12

    p (x) = r (x) - c (x)

    ⇒ p (x) = 8x - (3x+12)

    ⇒ p (x) = 8x-3x-12

    ⇒ p (x) = 5x-12

    Hence, Correct option is:

    D) p (x) = 5x-12

    Answer: Seeing that you have to subtract c and r you subtract the 3x from the 8x and also subtract 12 from 0 and you get P (x) = 11x--12
