Liana Stokes · Answer 1

The correct answer is B) the cost of removing 80% of pollutants is $196,000.

Using the equation, we have

240 (80) / (100-80) = 240 (80) / 20 = 196

Since this is in thousands of dollars, we have 196,000.

Using the equation, A is not correct; it would be 160,000.

The vertical asymptote would be at 100%.

B must be the correct answer.
