The cost in millions to remove x% of pollution in a lake modeled by
C=6000/200-2x.
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?

  • Algebra (please help me) - ,

    C=6000/(200-2X) I'LL ASSUME THIS IS THE EQUATION.
    C=6000/(200-2*75)
    C=6000/(200-150)
    C=6000/50
    C=120 COST TO REMOVE 75%.
    C=6000/(200-2*90)
    C=6000/(200-180)
    C=6000/20
    C=300 COST TO REMOVE 90%.
    C=6000/(200-2*99)
    C=6000/(200-198)
    C=6000/2
    C=3000 COST TO REMOVE 99%.
    THE EQUATION IS UNDEFINED WHEN YOU USE 100%.
    C=6000/(200-200)
    C=6000/0 C BECOMES UNDEFINED WHEN YOU DIVIDE BY 0.
