文章最后一段最后一句(从A study has shown that if the registeration discount is equal to at least half the potential savings of an antendee's particular cost-saving strategy, the attendee is much more likely to reserve a room within the block.)手打的,请各位忽略拼写错误。 我的疑问是,这里说了,如果酒店在注册费用上的discount至少等于ROB节省下来的钱的一半的话,那么顾客还是会定block的房间的。 那问题是1C中,ROB比block便宜783-758=25,而discount也是25。discount都等于saving了,为什么还ROB呢??
