某业主贷款2.2万元购进一台机器,生产某种产品,已知的成品是5元一个,售价为8元一个,应付的税款和其他费用是售价的10%

设空调进价为x 电风扇的进价为y 根据提议得
18x+20y=17400
10x+30y=22500
解题得 x=211.77 y=679.4
答:空调211.77元 风扇每台679.4元
出这道题的人脑袋一定让驴踢了

“且”是并列的关系,必须同时满足两个条件才能成立
为了计算简便,比如小区业主600户,面积6000平米,那么得有占面积三分之二的业主同意,就是4000平米的业主,但是还得满足一个条件是这4000平米的业主总人数得400户以上,因为有这样的可能,也许有一户就占了1000平米.

π（2×1000）×（2×1000）-π（3×100）×（3×100）=3.91×1000000π
=12277400 cm²
=1227.74m²
（取π=3.14）

解题思路：（1）挂式空调价格×台数+电风扇价格×台数=总价，列出二元一次方程组，解答；
（2）挂式空调单价×台数+电风扇单价×台数≤总价，挂式空调利润×台数+电风扇利润×台数≥总利润，列出一元一次不等式组，解答；

（1）设挂式空调每台的价格是x元，电风扇每台的价格是 y元，
根据题意得：

8x+20y=17400
10x+30y=22500，
解方程组得：

x=1800
y=150；
答：挂式空调每台的价格是1800元，电风扇每台的价格是 150元．
（2）设购买挂式空调z台，则电风扇70-z台，
根据题意得：①200z+30（70-z）≥3500，
②1800z+150（70-z）≤30000；
由①②解得：8.2≤z≤11.82，
因为z为整数，所以一共有3种进货方案：
①当购买挂式空调9台，电风扇61台时，利润是：200×9+30×61=3630元，
②当购买挂式空调10台，电风扇60台时，利润是：200×10+30×60=3800元，
③当购买挂式空调11台，电风扇59台时，利润是：200×11+30×59=3970元，
所以，当购买挂式空调11台，电风扇59台时，利润最大，最大利润是3970元．

解题思路：先设乙公司每年租金比前一年增长的百分率为x，根据乙公司三年内的总租金比甲公司多2千元列出方程，再求出x的值即可．

设乙公司每年租金比前一年增长的百分率为x，根据题意得：
20+20（1+x）+20（1+x）²-29×3=0.2，
解得：x₁=[2/5]，x₂=-[17/5]（舍去）；
则乙公司后两年的租金分别是20×（1+[2/5]）=28（万元）和20×（1+[2/5]）²=39.2（万元）；
答：乙公司后两年的租金分别是28万元和39.2万元．

（1）设空调价格x,电扇价格y.
则8x+20y=16800
10x+30y=21600
解得x=1800,y=120
（2）由题意设购买空调a台,则风扇100-a台
1800a+120（100-a）≤60000
350a+30（100-a）≥11200 ；
解不等式组得25/8≤a≤200/7,因为a为正整数,所以有解（a=5,6,7,……,28）共24种方案
获得利润最大的情况是a=28时,可以获利350*28+30*（100-28）=11960
第二题的最佳方案就是买28台空调,72台电扇

Abstract
物业管理服务费既是保证物业管理活动正常运转的动力,也是涉及业主、物业使用人切身利益的大事,因此备受业主、物业使用人和物业管理企业的关注.
The service charge of property management is not only the power that guarantees the normal operation of property management activities,but also the important issue that is involved in the personal interest of proprietors and property users; therefore it draws great attention from the proprietors,property users and property management enterprises.
目前物业管理收费难,纠纷日益增多,焦点大都集中在业主或使用人认为有关服务费项目不合理、服务质量不合格,物业管理公司则认为业主或使用人不按时交纳物业费,不遵守物业公约.
Currently,it is hard to collect the service charge of property management,and thus more and more disputes are arising from this issue.Mainly,most proprietors or property users argue that the service charges are unreasonable and the service quality is unqualified,while the management companies believe that the proprietors or property users do not pay the service charges on time and do not abide by the agreement of property management.
因此,如何解决物业管理收费难就成为物业管理企业面临的重要难题.
Therefore,how to deal with the tricky issue of collecting the service charges of property management has become the critical problem that is confronting the property management enterprises.

有失偏颇。尽管固定总价合同中材料价格的风险由承包商承担。但是如果合同期原材料价格下降的情况下，采取规定固定总价合同并不对业主有利。当然如果价格上升则肯定对业主有利，不过如果价格上升的离谱，承包商可向法...

甲工程队单独完成此项工程需50天,甲的工作效率就是150,甲工作了10天,就完成了整个工程的150x10=15 ,剩下1—15=45,在剩下的工程中甲完成了150x15=310,乙就完成了整个工程的45--310=12,所以乙完成整个工程的时间是15（12）=30天
15（1—150x10--150x15）
= 15(45--310)
= 15(12)
= 30天

Through to the owner and the door model analysis understands,this door ventilated daylighting is good,only to kitchen door to shift the demolition,to avoid the toilet with the kitchen door to death.Then in not large space design gives a lot of space in feeling,fully meet the requirement of owner.For the bedroom,only request not too complex,simple,sweet primarily.This door 90 square meters,usable floor area also has more than 60 square meters,the space is not large.Toilet less than 6 square meters,advocate lie 11 duopingmi,second lie not 9 square meters,the floor to the sitting room scarecely for 29 flat,kitchen 3 square meters,the balcony is longer,more than five square meters.

设这件服装进价为x元,如果以高出进价50%标价
（1+50%）x=200
X≈133
如果老板以高出进价的100%标价,则
（1+100%）x=200
X=100
可见进价在100~133元之间,因此还价范围可定为
100（1+20%）~133（1+20%）,即120~160元之间
