Step-by-step explanation:
Yes.  Percent of change is the amount of change divided by the initial value.
% of change = (final − initial) / initial × 100%
If the change is greater than the initial value, then the percent change is greater than 100%.
For example, if the price of something triples from $1 to $3, the percent of change is:
% of change = (3 − 1) / 1 × 100%
% of change = 200%
