The final answer is $71,387,708,456.80
First, you plug the variables into the equation.
[tex]11600000(1 + 6.9) ^{5} [/tex]
The answer to that is 356,938,542,284. This is the total amount that is due at the end of the five years.
You then divide that by 5 to get the amount paid each year, thus leaving you with $71,387,708,456.80
