Andrew Reeson, aged 22, is about to begin his carrier as an economist for the Treasury. Being an econamist, Andrew knows he should begin saving for retirement immediately. Part of his inspiration came from reading an article on retirement funding in the Australian Financial Rivew. The article indicated that the ratio of workers paying tax to retirees collecting pensions will drop dramatically in the future. In fact, the number will drop to two workers for very retiree by 2040 . Andrew's retirement plan allows him to make yearly contributions, and it pays 9% interest annually. Upon his retirement at age 65 (in 43 years), Andrew plans to buy a new boat, which he estimates will cost him $300,000. He also estimates that in order to live comfortably he will require a yearly income of $80,000 for each year after he retires. Based on his family history, Andrew expects to live until age 80 (that is he would fike to receive 15 payments of $80,000 at the end of each year). When he retires, Andrew will purchase his boat in one lump sum and place the remaining balance into an account that pays 6% annual nterest, from which he will withdraw $80000 per year. If Andrew's first contribution is made one year rom today and his last is made the day he retires, how much money must he contribute each year to is retirement fund? [ 15 marks]
