You just graduated from college and landed your first "real" job, which pays $35,000 a year. In 13 years how much will you need to earn per year to maintain the same purchasing power if inflation is 1.75% per year?

You are 65 years old and about to retire. You have $100,000 saved in a retirement account and would like to withdraw it in equal annual amounts so that nothing is left after 6 years. How much can you withdraw each year if the account earns 4% interest each year?
