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 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)**
