Store A is offering Karen’s favorite jeans at 15% off their regular price of $25. Store B is offering the same pair of jeans at 25% off their regular price of $30. At which store should Karen buy her jeans?
Store A is selling the jeans at 85% of $25 = $21.25
Store B is selling them at 75% of $30 = $22.50
I'd go with Store A.....
