Final answer:
The percent of change is 64%.
Step-by-step explanation:
To calculate the percent of change, you can use the formula:
Percentage change = (Change in amount / Original amount) * 100
In this case, the original amount is 25 and the change in amount is 41 - 25 = 16.
So, the percentage change = (16 / 25) * 100 = 64%
