Answer:
No, he is not correct
Explanation:
Evan said that he did 125% more in the second week.
So, it must be like 125% of 20 + 20 (Because he did 20 hours of work in the first week)
Now, Let's see whether it equals 25
=> 125% * 20 + 20
=> 125/100 * 20 + 20
=> 1.25*20 + 20
=> 25 + 20
=> 45
So, No, he is not correct
Rather he spent 25% more hours doing homework next week.
