答案中这样一段话，
outstanding account are paying more slowly since the average colleciton period is up,我的理解是这里的collectperiod应该用公式，receviable turnover =annual sales / average receivable, days of sales outstanding =365/receviable turn over，那么period up ，turnover就应该下降，那么 annual sales / average receivable,下降
Blockdnick has a less creit outstanding since the days of receviable down, so creidit sales are a smaller part of his business
这里是不是应该用公式，365/ receviable turnover =credit sales / average receivable ，days down，那么turnover上升，就是credit sales / average receivable上升，
这样推倒出，应该是credit sales占的比重大了，怎么是less呢，哪位高人来给解答下呢？作者: b_sea93 时间: 2014-7-8 09:00
谢谢楼上的解答，不过这个公式是第四本书上的，我用了第三本书和第四本书上的不同的公式，因为我想根据第一段话的推倒，那么period up ，turnover就应该下降，那么 annual sales / average receivable,下降 和第二段话你的推倒 turnover则上升，average receivable则下降 这不是两个相反的结果么作者: ninja1024 时间: 2014-7-8 09:00
我觉得是理解的问题。
Blockdnick has a less creit outstanding since the days of receviable down, so creidit sales are a smaller part of his business
我的理解：这句话是说由于days of receviable down，因此推出了Blockdnick has a 减少的信用销售量，从而进一步推出信用销售在业务中占比变小。作者: Otabek 时间: 2014-7-8 09:01
