Answer: The correct answer is a 25% discount.
Step-by-step explanation: In order to calculate the percentage discount you need to first calculate the amount of the discount. This is done by subtracting the two numbers. $72 - $54 = $18. The amount of the discount is $18.
Next, you need to calculate what percentage the discount is of the original price. This is done by dividing the discount amount by the original price.
$18/$72 = 25%
This answer is the percentage discount.
