Mary wants to save money for his retirement. He would like to be able to retire 40 years from now with retirement income of US$17,000 per month for 25 years. Second, after she passes on at the end of the 25 years of withdrawals, she would like to leave an inheritance of US$1,600,000 to his nephew Mike. You can assume, that Mary is able to save regularly only for the 20 first years and nothing in years 20-40. Evaluate what should be the amount invested in the end of each year (for 20 years) to achieve these goals? You can assume that the interest rate is 3% throughout Marys lifespan.
