Did i do this right what do i have to fix

No, he is not correct

Step-by-step 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.
