Answer:
scenario one is matched to graph three
scenario two is matched to graph one
scenario three is matched to graph two
Explanation:
scenario 1 is the only one that decreases and graph 3 is the only decreasing graph.
scenario 2 is increasing by an unsteady amount so that matches graph 1 because it is increasing in a curve
so that leaves scenario 3 and graph 2 which both increase by a steady amount
Hope this helps! :)
