#### Explanation:

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

p% = (N - O)/O * 100

$p$ is the percent change

$N$ is the New Value.

$O$ is the Old Value

Take the old and new values you are given in the problem, substitute them for $O$ and $N$ and calculate the percent change
