**bobpursley**, Monday, September 26, 2011 at 10:51amI guess you have to explain what a cost decrease of four times means to you, since that is not a common math term.

What is a cost decrease of one time?

What is a cost decrease of two times?

It is total nonsense, and I am very surprised a "math" teacher is "teaching" such nonsense.

Now on the second point of nonsense. Is the phone free? A 100% decrease would make the phone zero cost. If it decreased more than that you should get paid to take a telephone.

You are at the wrong school. I hope you are not paying for this education.
