Suppose that you plan to retire 25 years from now with $300,000 and a cabin at the lake. For the next 10 years you plan to save $3,000 at the end of each year. At the end of 10 years you plan to buy a cabin for $40,000.
How much do you have to save each of the years 11-25 to have $300,000 when you retire? Assume that you can earn 10% per year on your savings.
