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?
1 Answer
Yes
Explanation:
120% = 1.2
If Maxine is correct, then she spent
15 * 1.2 = 18.0 = 18
"15 hours" * 1.2 = "18.0 hours" = "18 hours"
This means that Maxine is correct.
