During a sale, a pair of jeans is marked down from a selling price of $50 to a sale price of $30. What is the percent markdown?

40%

Step-by-step explanation:

To find the percent markdown, divide the new sale price by the initial price:

30/50 = 3/5 = 0.6

30 is 60% of 50. That means the value of the initial price dropped by 40% to become the sale price. This means that the percent markdown is 40%.

Hope this helps :)
