using the information what if you were able to contribute $100,$500 and $1,000 per month. How would this change the years untill you retired?

1) You are 20 years old, and you believe you can retire once you build up an investment account that produces enough passive income to support your annual expenses. You think you will need approximately $80,000 per year for your expenses. If your investments have a return of 10% per year, what is the minimum account balance you need to retire? If your investment account had an initial balance of $10,000, how long will it take before you can retire (assuming you don't have monthly or annual contributions)
