One way to do this is say that 399 is 100% Like this
399 is to 100 as 269 is to what or
399---100
269---x
(269*100)/399 or 67.418 % and the percent of change 100-67.418=32.581%
so if you round this you have 33%

change divided by original, times 100
So in this case, [(final_price - original_price) / original_price] * 100
[(269-399) / 399] * 100
or
-32.58%, which rounds to -33%
the negative indicates it is a DECREASE in value -- in most everyday circumstances you would just say that this is a DECREASE of 33% or a SAVINGS of 33%. But mathematically, it is more correct to say that it is a CHANGE (also called a DELTA) of -33%
"Percent" is a contraction of the Latin "Per Centum" which literally means "for every hundred" -- so finding a percentage change is finding how much something changes for every hundred.
When we divide the amount of change by the original value, we get the amount of change for every ONE (in this case, the price has changed by -$0.33 for every $1.00 of original value), and that is why at the end we must multiply the result by 100 to get percentage.

269 / 399 = percentage PAID for the tv = 67% (rounded)
100% - 67% = percentage of discount = 33%

399-269= 130
32% off ($127.68) = $271.32
33% off ($131.67) = $267.33

You would be getting 33% off if you purchase 399.00 minus 33% equals 267.33 dollars. So anywhere between 32-33%. Hope this helps.

I refuse to do your homework for you. Get a caculator and do it yourself. You can't use Yahoo! Answers as your tutor. You should be in school anyway. Your other question was retarded too.
