The cost in millions to remove x% of pollution in a lake modeled by
C=6000/2002x.
What is the cost to remove 75% of the pollutant?
What is the cost to remove 99% of the pollutant?
For what value is this equation undefined?

C=6000/(2002X) I'LL ASSUME THIS IS THE EQUATION.
C=6000/(2002*75)
C=6000/(200150)
C=6000/50
C=120 COST TO REMOVE 75%.
C=6000/(2002*90)
C=6000/(200180)
C=6000/20
C=300 COST TO REMOVE 90%.
C=6000/(2002*99)
C=6000/(200198)
C=6000/2
C=3000 COST TO REMOVE 99%.
THE EQUATION IS UNDEFINED WHEN YOU USE 100%.
C=6000/(200200)
C=6000/0 C BECOMES UNDEFINED WHEN YOU DIVIDE BY 0.
