Final answer:
To calculate the discount percentage, subtract the sale price from the original price to find the discount amount, then divide this by the original price and multiply by 100. The discount on the joggers is 12.5%.
Step-by-step explanation:
To calculate the discount percentage for the joggers, you need to determine the amount of the discount and then divide that by the original price.
First, find the amount of the discount, which is the difference between the original price and the sale price. The original price is $40 and the sale price is $35, so the discount amount is $40 - $35 = $5.
To find the discount percentage:
Divide the discount amount by the original price: $5 ÷ $40 = 0.125.
Convert this decimal to a percentage by multiplying by 100: 0.125 × 100 = 12.5%.
Therefore, the discount on the joggers is 12.5% off the original price.
