Let's suppose I need \$200,000 to pay a debt, no more, no less. So I placed a property to sell with an agent, but I know the agent will deduct 6% for himself, which will amount to \$12,000.
Since this will result in less money than what I need, through trial and error I calculated that I will need to sell it for about \$212,766 in order to receive \$200,000 on my hands.
Which formula could I use, instead of trial and error, to arrive at \$212,766, since $200000 + 6\%$ would still amount to less than the desired value?
