Question 107635: Suppose a cost-benefit model is given by:

y+=+2845%2F%28100-x%29




Where y is the cost for removing x percent of a given pollutant. what percentage of pollutant can be removed for $23,000.00?

You can put this solution on YOUR website!
y+=+2845%2F%28100-x%29 is your model, but you are given the value of y. So you have to rearrange the model equation so that it is expressed in terms of x.

100-x=+2845%2Fy
-x=+%282845%2Fy%29-100
x=+100-%282845%2Fy%29

Now, plug in your $23,000 for y and do the arithmetic. You should get an answer of roughly 88%.
