Need help with a b c d. Thanks

Let R(x), C(x), and P(x) be, respectively, the revenue, cost, and profit, in dollars, from the production and sale of x items. If R(x) = 6x and C(x) = 0.003x + 2.9x + 50, find each of the following. a) P(x) b) R(150), C(150), and P(150) c) R'(x), C'(x), and P'(x) d) R'(150), C'(150), and P' (150) a) P(x) = (Use integers or decimals for any numbers in the expression.) b) R(150) = $ (Type an integer or a decimal.) C(150) = $ (Type an integer or a decimal.) P(150) = $
