For this problem set, we are not going to give you the exact answer but a range within which the correct answer can be found.  For example, if the problem was “How much is 20 plus 50?” we would say, “The correct answer is between 65 and 75” and you would need to specify the exact answer of “70.”

Bola's friend Marshall heard a speech by John C. (Jack) Bogle, founder of The Vanguard Group of Mutual  Funds, one of the lowest cost and most successful group of funds.  Jack said that with the increasing need to reduce carbon emissions, it is unlikely that long term stock returns can exceed 6% per year.  Steps to reduce carbon will likely reduce prospects for economic growth in Mr. Bogle's opinion.  How much will Deniece have if Jack Bogle is correct and the earnings will be 6% per year compounded annually?
