Your Auntie Mary has a tendency to spend a lot. You decided to apply your financial skills and the use of a graph to show her how much she can save by habitually deposit $100 at the end of every month into her savings account for the next 30 years. Assume that she can earn a nominal annual interest rate of 4% in a deposit account that compounds interest every month in the next 30 years. Plot a graph that shows the accumulated savings in the 10th , 20th , and 30th years. Briefly explain your graph and clearly state your advice to Auntie Mary.
