1. After reading Elizabeth Warrens book, All Your Worth, you decide to be very careful about your LARGE purchases and commitments. As a result, you consistently choose a rent rate or a mortgage amount that is $100 less than you could afford. You also choose to pay cash for your cars to avoid $400 or more in interest expenses to finance a car purchase. In total, these choices save you $500 per month. How much can you accumulate if you save this $500 per month in an index fund that averages 9% per year for the 45 years you have until retirement? (Assume monthly compounding.)
