Graph the function and answer the question using graph.
Suppose the cost of cleaning contaminated soil from a dump site is modeled by C(x) , where C(x) is the cost (in $1000s) to remove x% of the contaminants. Graph using x [0,100], and use the graph to answer the following questions.
a. What is the significance of the vertical asymptote (what does it mean in this context)?
b. If EPA regulations are changed so that 85% of the contaminants must be removed, instead of the 80% previously required, how much additional cost will the new regulations add? Compare the cost of the 5% increase from 80% to 85% with the cost of the 5% increase from 90% to 95%. What do you notice?
c. What percent of the pollutants can be removed if the company budgets $2,200,000?
