Answer:
26%.
Explanation:
This is the formula you'll use for this type of problem. If your teacher wants you using a diff formula let me know. :P
Formula:
Discount percentage = (Discount amount / Original price) × 100%.
The original price of the item is $25, and after the discount, you only have to pay $18.50. The discount amount is not the end price, it is the amount taken away, so we subtract the discounted price ($18.50) from the original price ($25):
Discount amount = $25 - $18.50 = $6.50
Now, that we have that discount amount let's go back to that formula:
Discount percentage = ($6.50 / $25) × 100% ≈ 26%
Therefore, the discount on the item is approximately 26%.
