since the growth is increasing, there should be a common ratio between years
2100/2000 = 1.05
2250/2100 = 1.07
2315/2250 = 1.03
2431/2315 = 1.05
Seems kind of erratic, but maybe the best fit is 1.05 = 5% growth
The graph below shows the amount of money in one of Marie's savings accounts over several years. If Marie's savings continue to grow at the same rate as shown in the graph, how much money will she have saved by year 5 in this account?
The x axis of the graph is the years 0-4 and the y axis is the amount in savings from $2000-$2700. The points (0, $2000), (1, $2100), (2, $2250), (3, $2315), and (4, $2431) are marked on the graph. I know the formula and what to do to get how much money she will have, but I just need help finding the percentage, I can't seem to figure it out.
