You are trying to decide how much to save for retirement. Assume you plan to save $5,000 per year with the first investment made one year from now. You think you can earn 10% per year on your investments and you plan to retire in 43 years, immediately after making your last $5,000 investment.

- If, instead, you decide to withdraw $300,000 per year in retirement (again with the first withdrawal one year after retiring), how many years will it take until you exhaust your savings?

- Assuming the most you can afford to save is $1,000 per year, but you want to retire with $1,000,000 in your investment account, how high of a return do you need to earn on yoru investments?
