0.09 is the answer
here's how you do it:
0.89 times 12 is 10.68 subtract by 9.60 and get 1.08 then divide by 12 and get 0.09

me too its pointless unless you're going to be an architect or construction worker

or a engineer. but i don't think construction workers need alot of math education, do they? i always thought they needed a minimum education of mathamatics.

Don't underestimate the need for math beyond school.
That example could be used in your budget, in the grocery store, in drafting up a bit for pricing out a job.
Just test your teachers into giving real world examples to keep your interest.

My math:

$0.89 x 12 = $10.68
$10.68 - $9.60 = $1.08

TA-DA! :D

i forgot to divide by 12. so divide $1.08 by 12, and you get = $0.90.

It asked for the savings on just one notebook. You would do better in math if you read the problem carefully. And after you write it down read it again and check it again.
I'm not being sarcastic. I make so many mistakes because of this.
