There is a 44.4% increase from 9 trillion to 13 trillion.

Explanation:

Because both terms are in trillions we can drop the trillion and solve the problem as what is the percentage increase from 9 to 13.

The formula for determining the percentage change between two values is:

$p = \frac{N - O}{O} \cdot 100$

Where:

$p$ is the percentage change - what we need to determine in for this problem.

$N$ is the New Value - $13$ for this problem

$O$ is the Old Value - $9$ for this problem

Substituting and calculating $p$ gives:

$p = \frac{13 - 9}{9} \cdot 100$

$p = \frac{4}{9} \cdot 100$

$p = \frac{400}{9}$

$p = 44.4$ rounded to the nearest tenth.
