Answer: The sale price of the dress is $45.
Explanation:
To find the discount rate, we need to calculate the amount of the discount first. Since the dress is on sale for 25% off, the discount amount is:
Discount = 25% x $60 = $15
The discount rate is then calculated by dividing the discount amount by the original price of the dress and multiplying by 100:
Discount rate = ($15 / $60) x 100% = 25%
To find the sale price of the dress, we need to subtract the discount amount from the original price:
Sale price = $60 - $15 = $45
Therefore, the sale price of the dress is $45.
