# 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?

Dec 4, 2016

Yes

#### Explanation:

120% = 1.2

If Maxine is correct, then she spent $1.2$ times the hours she did homework than last week.

$15 \cdot 1.2 = 18.0 = 18$

$\text{15 hours" * 1.2 = "18.0 hours" = "18 hours}$

This means that Maxine is correct.
