M3D1: Saving for retirement

I don’t know how to handle this Mathematics question and need guidance.

Module 3

stacks of coinsAnswer the following questions.
(Note: You don’t need to reveal private information here—your answers to questions 1 and 2 can be any numbers you choose and need not be about your true age and finances.)

  1. How old are you now? At what age do you hope to retire? These questions are really about answering: How many years do you have until you retire?
  2. Based on how you want to live in retirement and any other sources of retirement income you have available, how much money do you think you will need to draw from this savings account each year during retirement?
  3. You are about to set up a new retirement savings account that earns interest at a 3.9% annual interest rate (APR). You want to make monthly contributions to that account from now until you retire. The goal is to save enough money so that you will be able to withdraw the money you need each month without depleting your principal (in reality, you will probably deplete your principal gradually). How much money do you need to contribute to the account each month?
