You will deposit $$150$ each of the next five years $($the first deposit will occur one year from today, and there will be a total of $5$ equal deposits$)$ into an account that pays a $7\mathrm{.}55\%$ effective annual rate. Six years from today, you wish to have exactly $$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, as that will reinforce your understanding of how annuity timing works.
