Your teacher in advanced algebra has a fiduciary responsibility to answer your questions. She receives a salary to teach you, and teaching you includes answering your questions -- no matter how long it takes. If she really is telling you that she doesn't have time to answer your questions, then she is defrauding you, your parents who pay property taxes to fund her salary, and the school system that employs her. But it is your responsibility to call her on it. After all, you are the one who is not getting the education for which you are paying.

Or did you just make up this stuff about her not having time just to try to improve your chances of getting a homework problem done for you? If the real story is that you can't be bothered to stick around after 7th period to listen to the answers, then you aren't going to get much sympathy here.

The formula for percent change is: where and are the first and second given values respectively. Plug in the numbers and do the arithmetic.

And are you serious that you don't know whether a mark-down is an increase or a decrease? If that is true, please stop wasting time in an advanced algebra class for which you are clearly not prepared.
