You have just made your first $5,000 contribution to your individual retirement account. assuming that you earn in the stock market an annual rate of 9.75% and make no additional contributions, what will your account be worth when you retire in 45 years? what if you wait 10 years before contributing? does this suggest an investment strategy?

After graduation, you plan to work for dynamo corporation for 12 years and then start your own business. you expect to save and deposit $7,500 a year for the first 6 years (t = 1 through t = 6) and $15,000 annually for the following 6 years (t = 7 through t = 12). the first deposit will be made a year from today. in addition, your grandfather just gave you a $32,500 graduation gift which you will deposit immediately (t = 0). if the account earns 9% compounded annually, how much will you have when you start your business 12 years from now?
