题目是什么意思？我是随便做的。10000×0.2肯定错了。

1000*0.5%+2000*1%+3000*1.5%+4000*2%=5+20+45+80=150

麻烦你能不能发我一个PREP数学链接呀，sky.2008[在] live.com 死活找不到。这题明天我再看，困了，先睡了。谢了

就是你在每个范围内能花的最多的money乘以bonus的百分比～～

i.e. 6,000到10,000的范围最多能花(10,000-6,000)。。。

What is the maximum annual bonus, in dollars? 题目的意思是在0.01-1000的时候收取0.5%的bonus,下面是各个区间对应的收取百分比，在每年年底，某信用卡公司都会根据用户持有的金额（最多到100000）pay a bonus,最初的1000基于0.5%，在下一个两千按1%，以此类推，最多可以达到多少？（即在达到100000时最大）

就是跟收个人所得税一样

意思是说，对第一个1000元消费给0.5%的Bonus，对1000元以上3000元以下的部分给1%的Bouns，依次类推。

如果你消费了10000元，则最初的1000元的获得1000*0.5%的Bonus，1000~3000元的那2000元获得2000*1.0%的Bonus，依次类推在加上 3000*1.5% 和 4000*2%。总计5+20+45+80=150

这个说法不对。注意原文说“A 0.5 percent bonus is paid on the first $1,000 charged, a 1.0 percent bonus is paid on the next $2,000 charged and so on”

个人所得税是只看总数落在哪个区间就按照那个区间对应的计算方法来算的。

yxydsy2007

A 0.5 percent bonus is paid on the first $1,000 charged, a 1.0 percent bonus is paid on the next $2,000 charged and so on,，

题目有说用差额算，可能还是英文，有时候反应不过来。

兄弟，PREP数学，只有讨论贴吗，在哪儿下载没答案的呢，我怎么么找不到呢
