Final answer:
To find the percent discount, subtract the discounted price from the original price, calculate the discount amount. Divide the discount amount by the original price and multiply by 100 to find the percent discount.
Step-by-step explanation:
To find the percent discount, we need to first calculate the amount of the discount. The original price of the item is $21, and after the discount, the price is $18.27. To find the discount amount, we subtract the discounted price from the original price: $21 - $18.27 = $2.73.
Next, we calculate the percent discount by dividing the discount amount by the original price and multiplying by 100: ($2.73 / $21) x 100 = 12.99%. So, the percent discount is approximately 12.99%.
