Final answer:
To calculate the percent of discount, subtract the sale price from the original price, divide the discount by the original price, and multiply by 100. Aimee received a 40% discount on the shirt.
Step-by-step explanation:
To find the percent of discount that Aimee received on the shirt, we first calculate the difference between the original price and the sale price. We subtract the sale price from the original price: $26.50 - $15.90 = $10.60. This is the amount of the discount. To find the percent of discount, we divide the amount of the discount by the original price and then multiply by 100 to convert it to a percentage.
The calculation is as follows:
($10.60 ÷ $26.50) × 100 = 40%.
So, Aimee's shirt has a discount of 40% off the original price.
