After some calculations, you realize that your inflation$-$adjusted retirement income shortfall is $$43,100$ per year.

You anticipate that once you retire, you will be retired for $34$ years. How much at a minimum should you have saved at the time of your retirement, if you estimate that your $60/40$ equity$/$debt retirement portfolio will have a real $($net of inflation$)$ return of $5\mathrm{.}97\%$ on average?

For simplicity, assume that once you retire you will be withdrawing the necessary amount from your portfolio at the end of each year.
