Given the original selling price of DVD player as $179.30 and the new sale price to be $144.77, the the first step in finding the percent markdown is to take the difference between the original selling price and the sale price to give $179.30 - $144.77 = $34.53
Percent markdown = original selling price- new sale price/original selling price × 100%
