Suppose that the cost C (in dollars) of removing p percent of the particulate pollution from the smokestacks of an industrial plant is given by 7000p C(p) = 100-p (a) Find the domain of this function. (Enter your answer using interval notation.) (b) Find the functional value. (Round your answer to the nearest cent.) C(43) = $ Explain what it means. C(43) is the ---Select--- ---Select--- of the particulate pollution from of removing the smokestacks of the industrial plant. (c) Find the functional value. C(90) = $ Explain what it means. ---Select- of the particulate pollution from C(90) is the ---Select--- of removing the smokestacks of the industrial plant. (d) Find the functional value. C(99) = $ Explain what it means. C(99) is the ---Select--- ---Select-- of the particulate pollution from of removing the smokestacks of the industrial plant. (e) Find the functional value. C(99.8) = $ Explain what it means. of removing ---Select- of the particulate pollution from C(99.8) is the ---Select--- the smokestacks of the industrial plant.
