Question

Marcus spent 10 hours doing his homework last week. This week he spent 11 hours doing homework. He says that he spent 110% more time doing homework this week. Is he correct? Show your work to justify your decision.

Plz help me! I think he is correct because 10% of 10 is 600 minutes= 1hr. so 10+1=11???? HELP! Giving medal and a fan.

Answer 1

No, he is not correct. I know this because he only spent 10% more time doing his homework this week.

Answer 2

Sure he is correct: proof: NOTE TAT 10HRS CORRESPOND TO 100%

1st week he worked 10 hrs, the 10% of 10 is 1 hr. Hence if he worked 11 hrs this week that means 10HRS (100%) + 1HR (10%) =110%
