SOLUTION: The cost, in millions, to remove x% of pollution in a pond is modeled by the equation: C= 6350/(425-3x). What is the cost to remove 75% of the pollution?

Question 467777: The cost, in millions, to remove x% of pollution in a pond is modeled by the equation:
C= 6350/(425-3x).
What is the cost to remove 75% of the pollution?

Answer by gwendolyn(128) (Show Source): You can put this solution on YOUR website!
All that you need to do is plug the value for x, 75, into the equation provided.
C=6350/(425-3x)
C=6350/(425-3*75)
C=6350/(425-225)
C=6350/200
C=31.75
C is the cost in millions, so we have to multiply our value of C by a million to get the total cost.
31.75*1000000=31,750,000
So, it costs $31,750,000.
