Final answer:
The discount percentage is 40%.
Step-by-step explanation:
To find the discount percentage, we need to calculate the difference between the original price and the sale price, and then divide that difference by the original price.
The difference between the original price and the sale price is $490 - $294 = $196
The discount percentage is the difference divided by the original price: ($196 / $490) * 100 = 40%
