Question 105820: I could use some help please.I am taking an on line couase and this did not come out of my text book. It came off my on line test.

The question is For the following function,C computes the cost in millions of dollars of implementing a city recycling project when x percent of the citizens particapte. C(x)=1.5x/100-x. Using this model approximately what is the cost if 60% ofthe citizens participate?
This is what I tried. C(60%)=1.5(60%)/100-60%, .9/66.66=.014 C=.014
Thank You for your help.
I found that I am totally lost
Answer by checkley75(3666) (Show Source): You can put this solution on YOUR website!
C(.6)=1.5*.6/(100-.6)
C(.6)=.9/99.4
C(.6)=.009 MILLION IS THE COST.
OR
C(.6)=1.5*.6/(100-60)
C(.6)=.9/.4
C(.6)=2.25 MILLION IS THE COST.
