Final answer:
To find the percent markdown of a DVD player, subtract the sale price from the original price to find the markdown amount. Then, divide this amount by the original price and multiply by 100 to get the percent markdown, which, in this case, is 15%.
Step-by-step explanation:
The first step in finding the percent markdown of a DVD player that was originally priced at $175.80 and is now on sale for $149.42 is to calculate the difference in price. This difference represents the amount of the markdown. To find this, you subtract the sale price from the original price:
Original Price - Sale Price = Markdown Amount $175.80 - $149.42 = $26.38
Next, to find the percent markdown, you divide the markdown amount by the original price and then multiply by 100 to get the percentage:
Percent Markdown = (Markdown Amount / Original Price) × 100
Percent Markdown = ($26.38 / $175.80) × 100
Percent Markdown = 0.15 × 100
Percent Markdown = 15%
Therefore, Karen's DVD player has a 15% markdown from the original price.
