Answer: NO
Step-by-step explanation: No, he is not correct. Because if you are expected to do 10 hrs that's 100% and if you go over by 1 hour, that hour would be equivalent to 10% because 100 divided by 10=10. So when Marcus says he spent 110% MORE time doing his homework, that is incorrect because 110%=11 EXTRA hours doing his work. The correct answer would be 10% extra since he only went over 1 hour.
