    Did you leave out some information?

    Re-check your problem. I think you are missing a part here.

    pollution in a lake modeled by ?

  • Algebra - ,

    sorry it didn't paste the formula.. lets try again....

    1. The cost, in millions of dollars, to remove x % of pollution in a lake modeled by C=6000/(200-2x)

    a. What is the cost to remove 75% of the pollutant?

    I got $3,022,670,025

  • Algebra - ,

    C = 6000/(200 - 2x)
    C = 6000/(200 - 2(75))
    C = 6000/(200 - 150)
    C = 6000/50
    C = 120 mil
    120,000,000 million

    or, is it

    C = 6000/(200 - 2(.75))
    C = 6000/(200 - 1.5)
    C = 6000/198.5
    C = 30.2267 mil
    30,226,700 million

    I think it's the first, but I am not a tutor
