Question: COST OF REMOVING TOXIC WASTE A city's main well was recently found to be contaminated with trichloroethylene, a cancer-causing chemical, as a result of an abandoned chemical dump leaching chemicals into the water. A proposal submitted to the city's council members indicates that the cost, measured in millions of dollars, of removing x% of the toxic pollutant is given by
C(x) = 0.5x
100 - x
Find C'(80), C'(90), C'(95), and C'(99). What does your result tell you about the cost of removing all of the pollutant?
