Khianna went shopping for her outfit for a dance at the school. She planned to buy shoes, jewelry, nail polish, makeup, and a dress at the mall. At one store she bought nail polish for $4.79 and makeup for $21.45. At another store she bought shoes for $26.43. At a third store she bought her dress for $168.27. She calculated that she spent $389.21. Is this reasonable? Why or why not?
