Question

Maxine spent 15 hours doing her homework last week. This week she spent 18 hours doing homework. She says that she spent 120% more time doing homework this week. Is she correct? Show your work to justify your decision.

Answer 1

can you help me plz???

Answer 2

20% of 150 is 30
The only thing that makes maxine incorrect is the fact that she says it was 120% more than last week. That would mean she did 18 more hours than last week.
That would mean that she would have done 33 hours of homework this week.
If she said she just did 120% hours worth of homework she did last week, then she would be right
