Since the image for the graph is not clear, i have drawn the graph and attached with the solution. With the graphs shown in the question, the correct graph is TOP RIGHT graph.


$15,000 is expected after 15 years.
as shown in the explanation above at t=15, A=15000 (rounded off)
NOTE: since the question was blurred, the year for getting A= 18,000 is marked in the graph.Kindly ignore it.
15000 15.000 10 000 10000 5000 (c) Use the graph of An to determine when this...
