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. Write the data from the table as ordered pairs (x, y), where x represents the time and y represents the amount dissolved.
A. (1, 16.0), (2, 18.4), (3, 20.4), (4, 22.4), (5, 24.2)
B. (0, 16.0), (2, 18.4), (4, 20.4), (6, 22.4), (8, 24.2)
C. (2, 16.0), (4, 18.4), (6, 20.4), (8, 22.4), (10, 24.2)
D. (16.0, 2), (18.4, 4), (20.4, 6), (22.4, 8), (24.2, 10)
