Final answer:
The discount is 25%.
Step-by-step explanation:
To find the percentage discount, we need to calculate the difference between the original price and the discounted price, and then divide that difference by the original price. In this case, the original price is $36 and the discounted price is $27, so the difference is $36 - $27 = $9. Now we divide $9 by $36 and multiply by 100 to get the percentage: (9/36)*100 = 25%. Therefore, the discount is 25%.
