Ms. Sue,
Did you leave out some information?

Recheck your problem. I think you are missing a part here.

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/(2002x)
a. What is the cost to remove 75% of the pollutant?
I got $3,022,670,025 
Algebra 
helper,
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
