1. The cost, in millions of dollars, to remove x % of pollution in a lake modeled by C = __6,000__ (all supposed to be underlined)
3003x
a. What is the cost to remove 75% of the pollutant?
b. What is the cost to remove 90% of the pollutant?
c. What is the cost to remove 99% of the pollutant?
d. For what value is this equation undefined?
e. Do the answers to sections a. through d. match your expectations? Explain why or why not.

Type divisions this way ...
C = 6000/(300x)
a) replace x with 75
C = 6000/(3003(75))
= 6000/75 = 80
b) you try it, should get 200
c) should be really high
d) what happens when x = 100 ?

For A...I have 80million
B...200million
C...58 million

c)
C = 6000/(300  3(99))
= 6000/3
= 2000 million

ok i did it like this:
6000/(3003*99)
oh!!! never mind got it now..thank you!!!!
