K 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) = 4x and C(x) =0.004x +1.8x +70, find each of the following. a) P(x) b) R(100), C(100), and P(100) c) R'(x), C'(x), and P'(x) d) R'(100), C'(100), and P'(100) a) P(x)= (Use integers or decimals for any numbers in the expression.) b) R(100) = $ (Type an integer or a decimal.) C(100) = $ (Type an integer or a decimal.) P(100) = $ (Type an integer or a decimal.) c) R'(x) = (Type an integer or a decimal.) C'(x) = (Use integers or decimals for any numbers in the expression.) P'(x) = (Use integers or decimals for any numbers in the expression.)
