Question

Maxine spent 12 hours doing her homework last week. This week she spent 18 hours doing homework. She says that she spent 167% more time doing homework this week. Is she correct? Show your work to justify your decision

Answer 1

Explanation:

Last week Maxine spent 12 hours doing her work.

Assume that 12 hours is 100% of her "time".

18/12 = 1.5

1.5 x 100 (To find the percentage)

= 150

Therefore Maxine didn't spend 167% more time doing her work.
