Answer:

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.

The principal P is borrowed and the loan's future value A at time t is given. Determine the loan's simple interest rate r.
Virty [35]

A = P + SI

A-P = SI

5425-5000 = 425

THEREFORE THE SIMPLE INTRESTE IS $425

SI = PTR/100

425 = 5000×1×R/100

425×100/5000×1=R

425×100÷5,000×1 = 8.5%

THEREFORE THE RATE IS 8.5%
