Guilin Smile Hall is holding a promotional activity. Brand A skirts get 100 yuan off when they spend 200 yuan, and brand B skirts are "discounted up". That is, a 40% discount is given first, and a 5% discount is added on top of that. If both brands have a price tag 240 yuan skirt, which skirt is cheaper? How much cheaper?
桂林微笑堂搞促销活动，A品牌裙子满200元减100元，B品牌裙子"折上折"，就是先打六折，在此基础上再打九五折，如果两个品牌都有一条标价240元的裙子，哪条裙子便宜？便宜多少钱？
