Answer:

Evan is not correct, because it seems like he thought 25 is 125% of 20. He did not spend 125% more time doing homework this week because it was like he added an extra 100% from his 25 hours of homework he did. Because of this 100% increase, the correct answer is actually 25%.

Step-by-step explanation:

THE CORRECT ANSWER IS 25%
