Suppose the Cost C of Removing P Percent of the Particulate

question 24

Multiple Choice

Suppose the cost C of removing p percent of the particulate pollution from the exhaust gases at an industrial site is given by . Because p is the percent particulate pollution, we know . Use the restriction on p and experiment with a C-range to obtain an accurate graph of the equation. Determine the p-intercept and explain its meaning. ​

• A) The p-intercept is (0,0) , meaning that it costs nothing to remove all of the particulate pollution.
• B) The p-intercept is (0,72), meaning that there is a cost of $72 before the removal of the particulate pollution begins.
• C) There is no p-intercept, which means that it is impossible to remove all of the particulate pollution.
• D) The p-intercept is (0,0), meaning that it costs nothing to remove none of the particulate pollution.
• E) The p-intercept is (0, -72), meaning that there is a negative cost of $72 before the removal of the particulate pollution begins.
