A graph of the data that was collected is shown: A line graph with Number of Months on the x axis and Number of Users, in thousands, on the y axis. The x axis has a scale from 0 to 27 in increments of 3. The y axis has a scale of 0 to 22 in increments of 2. A straight line connecting 0, 20 and 24, 15.5 is drawn.
