Anuradha Dixit just turned 50. Anuradha is planning to retire in 15 years, and she currently has $30,000 in her pension fund. Based on the longevity pattern of her family, . how much will Anuradha have to save annually for the next 15 years? Solve the problem 1) by constructing a table similar to the "FUNDING2" tab from Lecture1 and using solver, 2) by directly using PMT function . Calculate the required annual saving if the interest rate ranges from 0% to 20% with 1% increments. Draw a graph that shows the required saving with respect to these values of interest rate. Make sure you build a model that looks good in addition to being correct. For the graph, use proper labels and title
