Problema Solution
Environmental and wildlife preservation ensures future generations will have available resources and can enjoy the beauty of Earth. On the other hand, some of the damage human beings have already done to the environment is expensive and time-consuming to reverse. Over-consumption of resources could also lead to a catastrophic decline of the population on Earth as early as in 2350, as the experience of the Easter Island clearly indicates.

1. The cost, in millions of dollars, to remove x % of pollution in a lake modeled by (Hint: if it is 10%, substitute 10 instead of x, not 10% or 0.1). Round your answers to the nearest tenth of a million.
C = 6000(200-2x)
a. What is the cost to remove 21% of the pollutant?
Solution:
(a)
When x=21, C = 6000(200-2*21) = 948,000 millions of dollars
So the cost to remove 21% of the pollutant is 948,000 millions of dollars
