Final answer:
The percent discount Magan received was calculated by finding the difference between the original price ($21) and the sale price ($12.60), which was $8.40. This discount amount was then divided by the original price and multiplied by 100 to get approximately 40% discount.
Step-by-step explanation:
To calculate the percent discount Magan received, we can use the formula:
Percent Discount = ((Original Price - Sale Price) / Original Price) × 100%
In this case, the original price is $21 and Magan paid $12.60. The discount amount is calculated by subtracting the sale price from the original price:
Discount Amount = Original Price - Sale Price = $21 - $12.60 = $8.40
To find the percent discount, we divide the discount amount by the original price and then multiply by 100 to convert to a percentage:
Percent Discount = ($8.40 / $21) × 100% ≈ 40%
So, the percent discount Magan received was approximately 40%.
