## 经济代写|微观经济学代写Microeconomics代考|SOLVING SIMULTANEOUS EQUATIONS

Company 1 has the attractive feature of a relatively low fee to unlock a scooter, but also the unattractive feature of a relatively high rate per minute. In contrast, Company 2 has a relatively high fee to unlock a scooter but a relatively low rate per minute. Someone who wanted to make a short ride (for example, 4 minutes) would do better under Company 1 (bill $=\$ 1.70$) than under Company 2 (bill$=\$2.60$ ) because the low fee to unlock a scooter for Company 1 would more than compensate for its higher rate per minute. Conversely, someone who wanted to make a long ride (say, 15 minutes) would do better under Company 2 (bill = \$4.25) than under Company 1 (bill$=\$5.00$ ) because Company 2 ‘s lower rate per minute would more than compensate for its higher fee to unlock a scooter.

Our task here is to find the break-even ride length, which is ride length for which the bill is the same under the two plans. One way to answer this question is to graph the two billing plans and see where they cross. At that crossing point, the two equations are satisfied simultaneously, which means that the length of the rides will be the same, as will the bills.

In Figure 1A.6, we see that the graphs of the two plans cross at $A$, where both yield a bill of $\$ 3.50$for a 10 -minute ride. The break-even ride length for these two companies is thus 10 minutes. If the length of your ride is longer than that, you will save money by choosing Company 2. For example, if you take a 20-minute ride, your bill under Company$2(\$5$ ) will be $\$ 1.50$cheaper than under Company$1(\$6.50)$. Conversely, if you ride for less than 10 minutes, you will do better under Company 1. For example, if you take a 5-minute ride, your bill under Company 1 (\$2) will be 75 cents cheaper than under Company 2 (\$2.75). For 10-minute rides, the two companies cost exactly the same (\$3.50). The question posed here also may be answered algebraically. As in the graphical approach just discussed, our goal is to find the point$(T, B)that satisfies both billing equations simultaneously. As a first step, we rewrite the two billing equations, one on top of the other, as \begin{aligned} &B=0.50+0.30 T \ &B=2+0.15 T \end{aligned} (Company 1). (Company 2). ## 经济代写|微观经济学代写Microeconomics代考|Supply and Demand The stock of foodstuffs on hand at any moment in New York City’s grocery stores, restaurants, and private kitchens is sufficient to feed the area’s 10 million residents for at most a week or so. Since most of these residents have nutritionally adequate and highly varied diets, and since almost no food is produced within the city proper, provisioning New York requires that millions of pounds of food and drink be delivered to locations throughout the city each day. No doubt many New Yorkers, buying groceries at their favorite local markets or eating at their favorite Italian restaurants, give little or no thought to the nearly miraculous coordination of people and resources required to feed city residents on a daily basis. But near-miraculous it is, nevertheless. Even if the supplying of New York City consisted only of transporting a fixed collection of foods to a given list of destinations each day, it would be quite an impressive operation, requiring at least a small (and well-managed) army to carry out. Yet the entire process is astonishingly more complex than that. For example, the system must somehow ensure that not only enough food is delivered to satisfy New Yorkers’ discriminating palates, but also the right kinds of food. There can’t be too much pheasant and not enough smoked eel, or too much bacon and not enough eggs, or too much caviar and not enough canned tuna, and so on. Similar judgments must be made within each category of food and drink: there must be the right amount of Swiss cheese and the right amounts of provolone, gorgonzola, and feta. But even this doesn’t begin to describe the complexity of the decisions and actions required to provide our nation’s largest city with its daily bread. Someone has to decide where each particular type of food gets produced, and how, and by whom. Someone must decide how much of each type of food gets delivered to each of the tens of thousands of restaurants and grocery stores in the city. Someone must determine whether the deliveries should be made in big trucks or small ones, arrange that the trucks be in the right place at the right time, and ensure that gasoline and qualified drivers be available. # 微观经济学代考 ## 经济代写|微观经济学代写微观经济学代考|求解联立方程 公司1有一个吸引人的特点是解锁滑板车的费用相对较低，但也有一个不吸引人的特点是每分钟收费相对较高。相比之下，公司2解锁滑板车的费用相对较高，但每分钟的费率相对较低。如果有人想要短途骑行(例如，4分钟)，在公司1(账单=\$1.70$)下会比在公司2(账单$=\$ 2.60$)下做得更好，因为公司1解锁滑板车的较低费用足以弥补其每分钟较高的费用。相反地，如果有人想要长途骑行(比如15分钟)，在公司2(账单= 4.25美元)下会比在公司1(账单为$=\$5.00$)下做得更好，因为公司2每分钟较低的费率足以补偿解锁滑板车的较高费用

## MATLAB代写

MATLAB 是一种用于技术计算的高性能语言。它将计算、可视化和编程集成在一个易于使用的环境中，其中问题和解决方案以熟悉的数学符号表示。典型用途包括：数学和计算算法开发建模、仿真和原型制作数据分析、探索和可视化科学和工程图形应用程序开发，包括图形用户界面构建MATLAB 是一个交互式系统，其基本数据元素是一个不需要维度的数组。这使您可以解决许多技术计算问题，尤其是那些具有矩阵和向量公式的问题，而只需用 C 或 Fortran 等标量非交互式语言编写程序所需的时间的一小部分。MATLAB 名称代表矩阵实验室。MATLAB 最初的编写目的是提供对由 LINPACK 和 EISPACK 项目开发的矩阵软件的轻松访问，这两个项目共同代表了矩阵计算软件的最新技术。MATLAB 经过多年的发展，得到了许多用户的投入。在大学环境中，它是数学、工程和科学入门和高级课程的标准教学工具。在工业领域，MATLAB 是高效研究、开发和分析的首选工具。MATLAB 具有一系列称为工具箱的特定于应用程序的解决方案。对于大多数 MATLAB 用户来说非常重要，工具箱允许您学习应用专业技术。工具箱是 MATLAB 函数（M 文件）的综合集合，可扩展 MATLAB 环境以解决特定类别的问题。可用工具箱的领域包括信号处理、控制系统、神经网络、模糊逻辑、小波、仿真等。
