1. I am 25 years old and would like to retire in 40 years when I am 65 years old. I would like to have $65,000 in my savings account at 3.9% interest. Also, that would be a savings of about $5,000 a month.

2) Suppose I do not retire at 65 years old and continue to work 6 more years until 71 years old. What would be the new annual income be then? What would be the new monthly savings each month? (at 3.9% interest)

3) Now, suppose you can find an account that earns 5.2% interest instead. How does that change your monthly payments?

4) How much interest are you earning in your 5.2% scenario?
