A dealer offers a computer software program whose list price is $500 at a 19% discount. She will give an extra 3% discount if paid in cash. What is the selling price if payment is made in cash?
If 500=81%, _____=78% (this comes from subtracting 19% from 100%, then subtracting the additional 3%
am i right

I don't exactly get what you are saying, but what I would do is find 19% of $500, and then subtract it from 500. Let's call that answer x. Then you find 3% of your answer, x, and subtract that, and you have your answer.
If you did that, or something similiar, then you'll probably be okay.
Hope I helped!
