Discount Percentage = (Marked Price - Selling Price)/(Marked Price) × 100%
Last Year:
Marked price = $7200
Selling price = $6120
Discount percentage = (7200 - 6120)/7200 × 100% = 15%
This Year:
Marked price = $6400
Selling price = $5600
Discount percentage = (6400 - 5600)/6400 × 100% = 12.5%
Therefore, the discount percentage last year is greater.

By the way,係另一個帖的意見欄,我指出了:
quadratic "formula" ≠ quadratic "equation"
quadratic "formula" 是用來 solve quadratic equation 的。
