See a solution process below:

The formula for calculating the percent change in a value between two points in time is:

$p = \frac{N - O}{O} \cdot 100$ $p = (N - O)/O * 100$

Where:

$p$ $p$ is the percent change - what we are solving for in this problem.

$N$ $N$ is the New Value - 98 in this problem.

$O$ $O$ is the Old Value - 70 in this problem.

Substituting and solving for $p$ $p$ gives:

$p = \frac{98 - 70}{70} \cdot 100$ $p = (98 - 70)/70 * 100$

$p = \frac{28}{70} \cdot 100$ $p = 28/70 * 100$

$p = \frac{2800}{70}$ $p = 2800/70$

$p = 40$ $p = 40$

There is a 40% increase from 70 to 98
