标题: 求助IR 1C [打印本页] 作者: 雍婷婷 时间: 2012-8-25 10:40 标题: 求助IR 1C 在题目中，有一句话是a study has shown that if the registration discount is equal to at least half the potential savings of an attendee's particular cost-saving strategy, the attendee is more likely to reserve the room within the block. 在1C中，HMHPA的registration discount是25，petential cost saving 是2*（104-79），为什么还要选rob stratagy 呢，想不通，求解答，万分感谢啊
