Answer:
Higher than 14%
Explanation:
The interest rate 'r' that would make both payments equivalent is given by the following expression.
[tex]1.3=1.0*(1+r)^2\\r=\sqrt{1.3} -1\\r=0.14=14\%[/tex]
Therefore, in order for it to be preferable to get the $1 million right now instead of $1.3 million in two years, the interest rate must be higher than 14%.
