Solve the problem.Suppose that during a certain step in a chemical manufacturing process the amount of hydrogen chloride 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 (6, 20.4) mean in the context of this situation?
A. (6, 20.4) indicates that 20.4 ppm of hydrogen chloride was dissolved after 6 seconds elapsed.
B. (6, 20.4) indicates that 20.4 ppm of hydrogen chloride was dissolved after 10 minutes elapsed.
C. (6, 20.4) indicates that 20.4 ppm of hydrogen chloride was dissolved after 6 minutes elapsed.
D. (6, 20.4) indicates that 6 ppm of hydrogen chloride was dissolved after 20.4 minutes elapsed.
