If an article costs a store $17.45 and if it sells the article for $22.95, what percentage markup is it using?

1.) Sales Price - Original Cost / Sales Price * 100 = Percentage Markup

2.) Now substitute the values:

Sales Price - Original Cost / Sales Price * 100 = Percentage Markup

$22.95 - $17.45 / $22.95 * 100 = Percentage Markup

$5.5 / 22.95 * 100 = Percentage Markup

...2397 * 100 = 23.97%

3.) Therefore, the store uses 23.97% as Percentage Markup
