Suppose a cost-benefit model is given by $C ( p ) = \frac { 5.8 p } { 100 - p }$ , where C is the cost in thousands of dollars for removing p percent of a given pollutant. Find C(90) to the nearest dollar and interpret it.
A) $5800; It will cost $5800 to remove 0.90% of the pollutant.
B) $5220; It will cost $5220 to remove 0.90% of the pollutant.
C) $52,200; It will cost $52,200 to remove 90% of the pollutant.
D) $9000; It will cost $9000 to remove 90% of the pollutant.

Plugging p = 90 into the given formula $C(90) = \frac{5.8 \times 90}{100 - 90} = \frac{522}{10} = 52.2$ thousand dollars, or $52,200, for removing 90% of the pollutant.
