104. Toxic pollutants.
The annual cost in dollars for removing P% of the toxic chemicals from a town’s water supply is given by the formula
C(p)= 5000,000/(100-p)<---did you mean 5 million or 500 thousand? I'm going with 5 million, if you meant 500,000, then remove a 0.
a. Use the accompanying graph to estimate the cost for removing 90% and 95% of the toxic chemicals.
I don't have your graph, but algebraically, this is how you'd to that:

1 million dollars!
If you're looking at the graph, go to x=95 and look up to see what y is there.
:
b. Use the formula to determine the cost for removing 99.5% of the toxic chemical

10 million dollars!!
c. What happens to the cost as the percentage of pollutants removes approaches 100%.
Anytime a denominator of a fraction approaches 0 the fraction approaches infinity.

Infinity!!!!!
Happy Calculating!!!
