The cost C, in dollars, to remove p percent of a certain pollutant from a pond is estimated by using the formula C = 100,000p/(100 - p). According to this estimate, how much more would it cost to remove 90 percent of the pollutant from the pond than it would cost to remove 60 percent of the pollutant?  Choose one.
A) $300,000 B) $100,000 C) $50,000 D) $10,000 E) $5,000
To remove 90% of pollutant   C= 100,000(90)/(100-90) = 900,000   To remove 60% of pollutant   C' = 100,000(60)/(100-60) = 600,000   Difference = C - C' = 300,000   $300,000nswer - $300,000
