(04.05)Evan spent 20 hours doing homework last week. This week he spent 25 hours doing homework. He says that he spent 125% more time doing homework this week. Is he correct? Show your work to justify your decision.

Answer 1

Answer:

Yes

Step-by-step explanation:

25% of 20 is 5. 100% + 25% (20 + 5)= 25.

Answer 2

Evans spent 25% more time doing homework this week. He is wrong by saying he spent 125% more

Number of hours Evan spent doing homework last week = 20 hours

Number  of hours Evan spent doing homework this week = 25 hours

Increase in the number of hours spent doing homework = 25 - 20

Increase in the number of hours spent doing homework = 5 hours

Percentage increase in the number of hours spent =

(Increase/Hours spent last week) x 100%

Percentage increase in the number of hours spent = (5/20) x 100%

Percentage increase in the number of hours spent = 25%

Evans spent 25% more time doing homework this week. He is wrong by saying he spent 125% more
