Hi,

The cost, in millions of dollars, to remove x % of the oil in the sea is modeled by 



C=12,000/300-3x 

C%28x%29+=+12000%2F%28300-3x%29

C%2880%29+=+12000%2F%28300-240%29=+200

C%2895%29+=+12000%2F%28300-285%29+=+800

C%2899%29+=+12000%2F%28300-297%29+=+4000

For what value is this equation undefined? when denominator = 0 , x+=+100

2. Provide an explanation of why it makes sense for the cost to undefined for the value found , based on what you know about pollution.

 Not possible to remove 100% of the Pollution
