Solve the problem.
-A power company burns coal to generate electricity. The cost C(x) (in $1000) to remove x% of the air pollutants is given by $\bar { C } ( x ) = \frac { 800 x } { 100 - x }$ If the power company budgets $1.2 million for pollution control, what percentage of the air pollutants
Can be removed? Round to two decimal places, if necessary.
A) 14.98%
B) 0.15%
C) 0.6%
D) 60%

To find the percentage of air pollutants that can be removed, set C(x) = 1200 (since $1.2 million is $1200 thousand) and solve for x:  $ \frac{800x}{100-x} = 1200 $  Solving this equation gives x = 60%.

Solve the Problem Cˉ(x)=800x100−x\bar { C } ( x ) = \frac { 800 x } { 100 - x }Cˉ(x)=100−x800x​

Solve the Problem $\bar { C } ( x ) = \frac { 800 x } { 100 - x }$
