Solve the problem.Suppose that during a certain step in a chemical manufacturing process the amount of hydrogen sulfide dissolved in a solution, measured in parts per million (ppm), is related to the elapsed time measured from the beginning of the step. Use the following table as a representation of this relationship. What does the ordered pair (9, 24.4) mean in the context of this situation?
A. (9, 24.4) indicates that 24.4 ppm of hydrogen sulfide was dissolved after 9 minutes elapsed. B. (9, 24.4) indicates that 24.4 ppm of hydrogen sulfide was dissolved after 9 seconds elapsed. C. (9, 24.4) indicates that 24.4 ppm of hydrogen sulfide was dissolved after 15 minutes elapsed. D. (9, 24.4) indicates that 9 ppm of hydrogen sulfide was dissolved after 24.4 minutes elapsed.
