How do I go about solving this...
The cost, in millions of dollars, to remove x% of pollution in a lake modeled by... C=6000/(200-2x). What is the cost to remove 73% of the pollutant? Round to the nearest millions of dollars.

Question

just replace x with 73

anonymous · Answer

so it would be, C=6000/(200-2(73))?

amistre64 · Answer

yep; and that simplifies down to whatever a calculator can give you :)  if that dont work, try .75.   but then the question should have been clearer if thats the case`

ok thank you

your welcome :)

So the answer I got was $$C=\frac{1000}{9}$$

yep, thats what it works out to be; so either its 111 or 30 :)
