把钱退回去 阅读题目 急!彭总担任国防部长期间,曾多次出国访问.每次出国,他都很节俭,从不多花一分钱.他经常对身边的工作

这个是C.一贷多借
具本分录：借：现金 270
差旅费 2730
贷：其它应收款 3000

解释：既然报销2730元，又退回了270元，说明当初借的是3000元，出差花费了2730元，剩下的270当然要退回财务部门了，所以现金要记增加，而其它应收款贷方记3000元，就把他当初借款时记入借方的3000地冲完了。

那一元根本不存在,这道题是把两个角度计算钱数混淆到一起了
最 初 abc每人支出10元,共30元,均在菜贩子手中
d讲价 菜贩子退回5元,剩下25元 d得到2元 共27元
abc每人拿回1元,相当于每人支出9元,共27元
PS：30-3*9=3,d又只拿走了2元,还剩下一元
30-3*9=3 这个3里面根本就不包括d得到的2元钱
这个式子应该解释为 abc原来拿的钱30-abc实际拿的钱27=abc拿回来的钱3
而 abc实际拿的钱3=菜农拿的钱+d拿的钱2,其中菜农拿的钱=原来30-退回5元
即 27 = （30-5）+2 说出错的环节应该就在于等式两边数量真正的含义吧

（1）面包利润 x-5
卖出个数 160-（x-7）*20
（2）上面两个相乘
（3）求二次函数最大值,求出顶点就可以了
x=1 时达到顶点,利润最大

In addition,as we all know,our administrative staff will also spend much time and energy to sort out the withdrawn products.

三人本来拿出来30元,后来一人退了1块,其实就是一共拿出来27元.
然后这27元中的25元交了房费,2元被服务员拿了

首先,最后一天青蛙是不往下划的.所以一定可以爬3米.剩余的井深部分,则每天爬3米,下滑2米.静爬高量3-2=1米.
5-3=2米,所以,青蛙用两天时间爬高了2米.第三天可以爬出井口.
所以答案是3天.

希望你采纳最佳答案,我花了三天三夜翻译的3.1 : abnormal verification3.1.1 this Division I received customer returned defective 3PCS, D / C were 0272 / 0166 / 9436, which were numbered 01 # 02 # 03 #, test its appearance has locking traces of products fan and its frame has a relatively thick dust, lead terminal are connected with the Department of electronic components, in addition 01 # products fan blade fracture 1PCS, 02 # products fan blade fracture 4PCS, 03 # products fan blade fracture 6PCS ( this type fan blade, a total of 7PCS). As shown below :3.2.1 respectively in 01 # 02 # 03 # further analysis, found the broken blade blade edge has the varying degree damage sag deformation, ( as shown below ), which is inferred for the fan in the high-speed operation when the upper edge of the blade and the other object body contact, leading to edge damage.3.2.2 further observations on its blade fracture, fracture analysis of traces left by the blade cracks highlight, fracture edges left deep right shallower, we conclude that for the left to right after the first force ; the other consists of fracture can be found on the edge of the lower edge is higher, therefore we can conclude that the upper edge for the first stress surface, after Wei downward edge, have further proved the upper edge and other objects have contact. In conclusion can be deduced : fan leaf is from left to right to fracture, namely to the running direction of the reverse side of the fracture, ( fan for counterclockwise movement). As shown below :Analysis of abnormal test : 3.33.3.1 from the above analysis can be inferred : fan blade fracture may be due to the fan at high speed operation ( this machine is a high speed rotating type, high), the fan blades and the other object collision contact, causing the fan blade by the reverse force and fracture.4.1.1 consists of blade fracture traces can be launched: fan at high speed operation with other objects in contact mechanics principle. According to the object in high speed operation, due to the relatively high speed, constant quality, speed of the kinetic energy is big, and other objects colliding will produce tremendous counterforce which leads to fracture.6.1.1 recommends that customers in the use of the fan when the fan blades and other objects to avoid contact and interference, which led to the blade damage.

有一个卖报的人,从报社买进某种晚报的价格是每份0.4元,卖出的价格是每份0.6元,卖不掉的晚报用每份0.2元的价格退回报社,每月以30天计.已知平时每天可卖100份,但双休日共八天每天可卖150份,若每天从报社买进的份数相同,卖报人应该每天从报社买进多少份报纸,才能获得最高利润.
设每天买进a张
100≤a≤150
那么每天剩下a-100张（平时）双休日不会剩下报纸
设利润为y
成本=0.4a×30=12a元
每个月卖出100×22+8a=2200+8a张
销售获得0.6×（2200+8a）=1320+4.8a元
卖不掉的晚报还可以获得（a-100）×0.2×22=4.4a-440元的补偿
y=1320+4.8a+4.4a-440-12a=880-2.8a
我们知道100≤a≤150
那么对于一次函数y=880-2.8a当a=100的时候
y取最大值y=880-280=600元

（1) 1,x

(1) y＝﹙1－0.6﹚X－(0.6－0.5)﹙100－X﹚
(2) 把y＝0代入得到X＝20,所以卖了20份.

The consignee required to return the payment for the goods that had been over paid.

I will return this lot of goods to you in due course,and I shall compensate you the costs of transportation.
很高兴能够帮到你,希望会对你有大帮助,

问题都不对,应该是每人10元,老板退了5元.服务员拿了2元,实际退回3元,每人就是交了9元,问：3*9+2=29..少一块钱.
实际上,不应该是+2的,因为那两块钱是服务员拿走的,记住,是拿走的.所以应该是 -2=25再加上老板的5元+5=30
也就是3*9-2+5

设批进x份,利润为y
y=20*150*1.5+(x-150)*0.4+10*100*1.5+(x-100)*0.4-30x*1
简化得y=5900-29.2x
要使利润最大,则x要最小,但是x最小不得低于150份,所以这个报亭应该每天从报社批进150份,才能使获得的月利润最高,最高利润为y=5900-29.2*150=1520(元).

当初他们三人一共是付了30元,可小弟退回每人1元,三人实际一共是付了27元.
这27元是这样的：老板收25元,小弟偷拿了2元!

这种算法当然不对了.
理由:(1)某三个秀才在一家客栈住房,结果每人10元,共10×3=30元.
(2)每人退回1元钱,即每人花了9元钱,三人一共花了27元钱.这27元里老板留下25元,小二私自留下2元.
(3)再加上退回的3元钱,结果正好是30元.
结论:这道题迷惑人主要是它把那2元钱从27元钱当中分离了出来,原题的算法错误的认为小二私自留下的2元不包含在27元当中,所以也就有了少1元钱的错误结果；而实际上私自留下的2元钱就包含在这27元当中,再加上退回的3元钱,结果正好是30元.

解题思路：因为每瓶付1.3元，每个空瓶钱比酒钱少1.1元，那么酒钱为（1.3+1.1）÷2=1.2（元），每个空瓶钱为3-1.2=0.1（元），进而求出6个空瓶钱．

每瓶酒钱为：
（1.3+1.1）÷2，
=2.4÷2，
=1.2（元）；
每个空瓶钱为：
1.3-1.2=0.1（元）；
6个空瓶钱为：
6×0.1=0.6（元）．
答：顾客应退回的空瓶钱是0.6元．
故答案为：0.6．

点评：
本题考点： 和差问题．

考点点评： 此题在求每瓶酒钱时，运用了关系式：（和+差）÷2=大数．

1.
每个面包的利润 = Y - 5
卖出的面包个数 = 160 -（X-7）*20 = -20X+300
2.
Y与X之间的函数关系式：即每个面包的利润 * 卖出的面包个数
Y = (X-5)*(-20X+300)
整理后得：
Y = -20X²+400X-1500
3.
Y = -20X²+400X-1500
整理后得：
Y= -20（X-10)²+500
即当面包单价定为10角(即X=10)时,该零售店每天销售这种面包获得的利润最大,最大利润为500角.

体温计与一般常用温度计相比,一个重要的不同点是,体温计可以（ 离开人体 ）读数,玻璃管中的水银不会自动地退回下面的玻璃泡.当用它测量过某人的体温,想再用它测另外一个人的体温时,必须先（ 甩一甩 ）.其他温度计则不能这样做.

并不是每人花了90元,每人真正花了(300-50)/3=250/3.
三人共花了250元加上每人退回的10元是280元,再加上女佣贪污的20元,正好是300元.

你算反了.这题很早就有了
给30退5块就等于花了25块,对吗?
又给了伙计2块,对吗?
那就说明总共花了25+2=27块,对吗?
3*9=27,对吗?
27=27,对吗?
还有什么好疑惑的?
这题的关键就在于你把伙计的2块加了两次

那一元钱让楼主拿去了,没有这样算钱的.
这30块钱的的分法是,三人3块,服务员2块,楼主25元.

（1）y=（1﹣0.5）x﹣（0.5﹣0.2）（200﹣x）
=0.8x﹣60（0≤x≤200）；
（2）根据题意得：30（0.8x﹣60）≥2000，
解得x≥ ．
159份报纸才能保证每月收入不低于2000元．

1.每月订购报纸30x,每份报纸利润0.3元）；
退回报社的报纸（30x-20*100-10*60份）,每份亏损（0.7-0.2=0.5元）；
每月利润y=0.3(20X+60*10)-0.5*10(X-60)=X+480 (60≤x≤100）
2.最大利润y=100+480=580.

实际上就不存在那二元
实际来说,每位客人付了十八元,一共付了54元,这54元老板得了50元,服务员私吞了4元 ,一分不多一分不少 .

（1）当x＜100时
y=30*x*（2-1.5）=15x 最大为1500
（2） 当100≤x≤150,所以
y= 20x（2-1.5）+10*100*（2-1.5）-10*（x-100）*（1.5-1）
=10x+500-5x+500
=5x+1000 （100≤x≤150） 最大是当x=150时 y=1750元
（3）
当x＞150时,每天都要退报纸,是不划算的.
y=20*150*（2-1.5）-20*（x-150）*（1.5-1）+10*100*（2-1.5）-10*（x-100）*（1.5-1）
=1500-10（x-150）+500-5（x-100）
=4000-15x
所以每天应该进150才能达到最高.
最高利润是 1750元.

只能说题目没有说清楚,退一本的情况,但从常识来看,如果是5元就只会退一本了,所以还是把5元给舍弃掉,直接就是6元；
