团购券 限2人使用 就是只能2个人就餐?不能3人?

用寡头市场价格刚性理论解释苹果产品的价格高居不下现象
最近IPAD2很火,三星,联想,HTC都出了PAD产品,但是苹果价格依然没有下降,用寡头垄断市场理论解释比较好
至于详细的就按照书上的理论来说就行了

团购属于薄利多销的经营方式,够了商家设定的人数,就可以走团购价了.我就团电影票,你要直接去电影院看电影,百八十的真正常,团购呢,30来块钱,多便宜!建议就是多去知名度高的网站,团一些人较多的东西!

团购
基本翻译
group purchase;
integrate purchase;
group buying
网络释义
团购:group purchase | buying in group | Groupon

解题思路：通过题意分析可以得出两个团的总人数要是不超过100人，费用最多13000元，而两团分别购票费用为13140元，所以两团人数超过100人，就可以求出两团的总人数，再设两个旅游团人数分别为x人、y人．由x+y=112，知x，y中至少有一个大于50．又由112×110=12320＜13140，可知x与y不会都大于50．再根据题意建立方程组求出其解就可以．

人数若不超过100人，费用至多13000元，所以，两个旅游团的总人数超过100人．
又10080÷90=112，知两个旅游团总人数为112人．
设两个旅游团人数分别为x人、y人．由x+y=112，知x，y中至少有一个大于50．又由112×110=12320＜13140，可知x与y不会都大于50．
若一个旅游团超过100人，另一个旅游团不足12人时，门票总钱数至多为9000+130×12=10560＜13140．
于是，可以断定有一个旅游团人数不超过50人，另一个旅游团人数超过50人但不超过100人．
不妨设1≤x≤50，51≤y≤100，则有：


x+y＝112
130x+110y＝13140，
解得：

x＝41
y＝71
∴两个旅游团的人数分别为41人和71人．

本题考点： 二元一次方程组的应用．

考点点评： 本题考查了列二元一次方程组解实际问题的运用及二元一次方程组的解法，不等式的运用，解答时根据题意求出两团的总人数是建立方程组的关键．

第一问：设下标1表示3人对苹果的消费；下标2表示2人对苹果的消费；P表示价格
e1=(dQ1/dP)*P/Q1=(dQ1/dP)*P/30=1/2
所以有dQ1/dP=15/P
e2=(dQ2/dP)*P/Q2=(dQ1/dP)*P/60=3/2
所以有dQ2/dP=90/P
e=(dQ/dP)*P/Q=[(dQ1+dQ2)/P]*P/Q=(15/P+90/P)*P/90=7/6
第二问：
由于e=7/6大于1,所以苹果的需求曲线是富有弹性的,当摊主实行降价时,可以增加苹果销售的总收入...

group+coupon
中文意思就是 团体+优惠券
自己揣摩,团体去购物是不是优惠呢?所以既是groupon.

720÷﹙160-100﹚=12

就是一个人使用一张的意思啦!（只是针对某些消费项目的,比如说美发啊什么之类的）可以两个人一起去的

设甲班x人,乙班y人,则
8x+10y=920
x+y=515
解得x=55 y=48

由题意知：设买6元的为X张,10元的则为（140-X）
（140-X）≥2X
因为问票价为6元的票购买多少张时所需的钱最少
所以当买6元的票最多时所需的钱最少
则（140-X)=2X时所需的钱最少
解之得：X=140/3
因为票价为10元的票数不少于票价为6元的票数的2倍
所以X=46
即票价为6元的票购买46张时所需的钱最少.

两张.因为可以两次.

720÷（160－100）＝12（张）

这是小学的算数,第一种76人团票为总金额¥1368. 而第二种办法取决于你有多少小孩?如果你76人中,小孩占了31个,则：（31x15)+(45x20) = $1365, 便宜3元.即小孩如果多于31人就比较优惠.

（1）设6人x桌,4人y桌.从608元可知,x+y>6 ,八折优惠.则
6x+4y=40
100x+80y=608÷0.8
∴x=2 y=7
答：6人2桌,4人7桌.
（2）∵6x+4y=40
∴y=10-3x/2
∵x+y>6
∴x+10-3x/2>6
∴x

720÷﹙160-100﹚=12

解题思路：便宜了百分之几，是求便宜的钱数占商场标价的百分之几，把商场标价看作单位“1”（作除数），用除法解答．

解；（4000-2400）÷4000，
=1600÷4000，
=0.4，
=40%；
答：小明妈妈上网购买这款电视比商场便宜了40%

3＋4＋5等于12
40除以5／12等于96本
96除以（1－1／5）等于120本
计算自己对一下,过程是这样的

Groupon was founded/established in November 2008,operating on group-purchase.Its unique tactic is to promote one and only one product a day,one bidding per person a day.Discount products must be of service basis,allocated regionally.Their off-line sales team is far bigger than online.

他们的人数不够30人,但是还是应该买30人的团购票,肯定比28人的散票便宜.多出两张,还可以卖给准备买票的散客.
