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.
