• Starting from your 65th birthday until your 84th, you would like to withdraw $50,000 per year (no plans for after that).
• The interest rate is 12%.

1. How much should you deposit in each of the initial years in order to fully fund the withdrawals?
2. How much should you deposit in each of the initial years in order to fully fund the withdrawals if you start saving at age 60? (More challenging) Set up the formula for the savings amount so that you can solve for various starting ages. Do a sensitivity analysis which shows the amount you need to save as a function of the age at which you start saving.
