In Silicon Valley, a number of computer-related manufacturing firms were contaminating underground water supplies with toxic chemicals stored in leaking underground containers. A water quality control agency ordered the companies to take immediate corrective action and contribute to a monetary pool for the testing and cleanup of the underground contamination. Suppose that the monetary pool (in millions of dollars) for the testing and cleanup is given by 2x P(x) = ,0 < x < 1 1- x where x is the percentage (expressed as a decimal) of the total contaminant removed. (A) How much must be in the pool to remove 90% of the contaminant? Answer (A) : In the pool must be millions of dollars (B) How much must be in the pool to remove 95% of the contaminant? Answer (B) : In the pool must be millions of dollars lim P(x) (C) Find x+1- and discuss the implications of this limit. Answer (C) : The limit is and that means
