A wealthy person named Mikail wants to make a donation to a charity that will provide the charity equal amount of payments (cashflow) for 10 years, with the first payment to the charity starting 1 years from today. Assume that the money that will be received by the charity will come from a bank account that provides 12% interest. And Mikail wants to put a single amount today in the bank that will generate equal payments of $5,000 to the charity for the mentioned 10 years. If the account already has $12,000 in it, how much additional amount will have to be deposited in the bank account today that will generate the required cash flows in the future?
