2. Retirement Planning. A couple will retire in 50 years; they plan to spend about $30,000 (real dollars) a year in retirement, which should last about 25 years. They believe that they can earn 8% nominal interest on retirement savings, and the couple realizes that the annual inflation rate is 4%.How much will they have to save each year for the next 50 years, in real dollars, to reach their retirement goal?
