can I get help thank you

$$$$$$$$$$ $$$$$$ I decided to start issuing bonds today totaling $16,000,000. I plan to pay these bonds back in three separate payments. The first payment will be 3 years from now for $5,000,000, the second payment will be 6 years from now for $7,000,000, and the final payment will happen 9 years from now. What will be the amount of this final payment assuming that I must pay 11% interest on their debt?
