Rachel turned 30 today and plans to retire at age 55, which is 25 years from today. She plans to save $12000 end of each year for next 25 years towards her retirement. She expects to receive a return of 6% per year. She expects to live until age 95. Under these assumptions, how much can she withdraw at the end of each of her 40 years in retirement ( that is withdraw from age 56 to 95).
