食宿占4分子1,购物占10分子3,路费占20分子9.

1-0.45-0.3=0.25 2000÷0.25=8000元
希望采纳

我帮你写好了.

First,we should make sure the toerism attractions where people expect and choose the city.
Then searching some information about tourism projects and accommodation price list,in order to prepare enough cash.
Querying the evaluaton about the tourist attractions,hotel accommodation,catering and entertainment network ,makeing the choice according to the evaluation toarrangements for the trip well.
Querying the travel line,transportation,general interest and economic standards to arrange travel mode.
You have prepared enough,let's pack up the necessary travel products to began the travel.

40%-30%=10% 车船费比食宿费多10%
450/5%*25%=2250 购物花了2250元
已知总费用为9000元,求车船费及食宿分别花了多少元?
9000*40%=3600
9000*30%=2700
求车船费,门票,购物以及食宿费用之间的比率
3600：450：2250：2700=8：1：5：6

（1）因为圆周角是360度
而购物在图中的表示是直角即为90度,所以购物的费用占整个支出的1/4
（2）花费在食宿上的费用应为8600*30%＝2580元
（3）路费占的比例为100%-1/4-30%＝45%
所以路费共用了8600*45%＝3870元

应是2000元
设食宿费用预算为X,则X(1+0.2)=600,X=500,
则总预算费用为500/25%=2000(元).

we will arrange your board and lodging,be at easy,it is our pleasure to give you a warm reception,we will meet you at airport.

设总支出为a,由题意得
1/4*a+3/5*a=3400
解得a=4000
即小明一家外出旅游的总支出为4000元

1总花费是多少?450/5%=9000
车费多少?40%*9000=3600

Good morning Sir (or Madam or XXX)! My name is Lihua, I am from XXX, It's good to be here, and I would like to apply the English tour guide, I like travel very much so I know what a person on a trip really needs and how to serve them better, further more learning and speaking English is one of my favorite my hobby so my English is well grounded, and I can speak a fluent English due to the frequent chatting with foreign friends trough phone or computer. I have a cheerful charactor, quick wittedness, and I good at communicating with people. I grew up in this city so I am fully familiar with the city history and culture.

姐、你这个 直接在网上下载“有道” 然后它能翻译好多种啦、而且百分百正确的、

根据题意可知食宿占总费用的百分比为100%-45%-30%=25%
（1）所以旅游总费用为3000/25%=12000元
（2）购物费用为12000*0.45=5400元
（3）2000/12000=0.167*100%=16.7%,如果此次旅游购物支出为2000元,那么购物支出占总费用的16.7%.

三人间是3*20=60元
二人间是2*30=60元
单人间是50元.
因为总共有20间客房,所以单人间越多越好,即三人间越多越好.
50/3=16...2
2间先住上单人间,于是住上了18间,所以还差2间.
最后2间从三人间里调剂.即把一间三人间拆成3间单人间.
最终有15间三人间,5间单人间.没有双人间.
15*60+5*50=1150元

1、食宿：5000*40%=2000
购物：5000*25%=1250
2、路费：5000*20%=1000
其他：5000*15%=750
1000-750=250,故路费比其他费用多250元
3、此次旅游食宿费用花销最大,花销为2000元,比其他多.
类似的信息可以得到很多~随便写~

If you could provide room and board,I could accept a monthly salary of 6000.

（1）东东一家这次旅游共花了9000元
（2）购物费用是（2700 ）元，交通费用是（3600 ）元。
（3）如果此次旅游的费用减少了1500元，而食宿费用不变，那么食宿费用占了总费用的36%

设降低x*100元,y（利润）=（4600-100x-3200）*10x=14000x-1000x方=-1000（x-7）方+49*1000,x=7函数取最大值,即收费标准=4600-700=3900利润最大
