You will deposit $150 each of the next five years (the first deposit will occur one year from today, and there will be a total of 5 equal deposits) into an account that pays a 7.7% effective annual rate. Six years from today, you wish to have exactly $1000 in the account. You would need to deposit an additional $_______ into the account six years from today to meet that goal. [Hints: Make a timeline! There are many ways to solve this problem, so you should be able to verify your answer by trying a different solution method. I recommend making sure you can solve this problem by starting it as an annuity problem.
