Question

Maxie spent 15 hours doing her homework last week this week she spent 18 hours doing her homework she says that she spent 120% more time doing homework this week is she correct

Answer 1

Answer: She's wrong.

Explanation:

Numbers of hours used in solving homework last week = 15

Numbers of hours used in solving homework this week = 18

Percentage increase = (18 - 15) / 15 × 100

= 3/15 × 100

= 1/5 × 100

= 20%

Since Maxie said that she spent 120% more time doing homework this week, she's wrong. She only spent 20% more.
