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.
Answer:
45%
Step-by-step explanation:
To find the percent, we write the information as part/whole:
99/220
Now we convert to a decimal by dividing:
99/220 = 99÷220 = 0.45
Lastly, multiply by 100:
0.45(100) = 45
Fun!
