Question

Removing Pollutants

The cost C (in dollars) of removing p% of the air pollutants in the stack emission of a utility company that burns coal is modeled by
C = 130,000p / 100-p     ,  0 ≤ p < 100.
(a)
Find the costs (in dollars) of removing 25%, 50%, and 75%. (Round your answers to two decimal places.)
cost of removing 25% of air pollutants $ =
cost of removing 50% of air pollutants $ =
cost of removing 75% of air pollutants $ =
(b)
Find the limit of C as
p → 100.
lim p→100 C =
