Question 1064932: Suppose an environmental agency decides to get rid of the impurities from the water of a polluted river. The estimated cost of removing x% of the impurities is given by the following formula. How much will it cost to remove 50% of the impurities?
C(x)= 5x^2+50/x(100-x) billion dollars
It will cost ___ billion dollars to remove 50% of the impurities.
(Round to two decimal places as needed.)
You can put this solution on YOUR website! C(x)= 5x^2+50/x(100-x)
Get rid of 50%, so x is 50
C(50)=5(2500)+50/(2500)=12500-.02=$12499.98 billion.
Note: I am assuming the second term is 50/(x(100-x)) with the parentheses as shown.
