Ecology The cost C (in millions of dollars) of removing p % of the industrial and municipal pollutants discharged into a river is given by C = 225 p 100 − p , 0 ≤ p < 100. (a) Use a graphing utility to graph the cost function. (b) Find the costs of removing 10 % , 40 % , and 75 % of the pollutants. (c) According to the model, is it possible to remove 100 % of the pollutants? Explain.
