The discount is 40%.
Selling price is defined as the price that a customer pays to purchase a product.
Selling price of dress is $58.80
The regular price of the dress is $98
Let the discount is x
So, sale price is x% lower than regular price =
98(100 - x)/100 = 58.80
So, (100 - x) = 5880/98
Or, x = 40
Hence, the discount is 40%
