10. Suppose the cost C of removing p% of the impurities from the waste water in a manufacturing process is given by
a) Where does the graph of this function have a vertical asymptote?
b) What does this tell us about removing the impurities from this process?
c) Removing how many percent of the impurities yield the cost of $10800?
Thanks in advance ;).

;). Thanks to anyone who tried, but i figured it out on my own.
If anyone is interested in the answer....
a) p=100
b) means they can't remove 100% of the impurities.
c) 18,00 = (3600p/100  p)
10,800(100  p) = 3600p
1,080,000  10,800 = 3600p
1,080,000 = 14400p
p = 75
removing 75% will cost $10800.
This is what i got, if i did anything wrong please correct me! 
Oops, typo.
10,800 = (3600p/100  p) ***
oh, and i just realized, the equation didn't show up when i asked the question.
Suppose the cost C of removing p% of the impurities from the waste water in a manufacturing process is given by C(p) = (3600p/100  p)**
