Article: Most MU charts have at least these three columns. There may sometimes be more, but these display the most crucial information. Typically, these are arranged from left to right. Note that the column headers will not always match these exactly. For example, the "Quantity" column may be labeled "Items bought," "Units purchased," or something similar. The important thing is the information in the column. A "classic" MU chart is often used to demonstrate that, as a consumer buys more of a certain good, the desire to purchase even more goods will drop. In other words, after a point, the marginal utility of each additional good purchased will start to decrease. Eventually, the consumer will start to be less satisfied overall than before buying the additional goods. In the example chart above, this trend of diminishing returns starts almost immediately. The first ticket to the film festival provides lots of marginal utility, but each ticket after the first gives a little less. After six tickets, each extra ticket actually has a negative MU, which decreases the total satisfaction. An explanation for this might be that, after six visits, the consumer starts to get tired of seeing the same movies again and again. This is the point where marginal price exceeds MU. A marginal utility chart makes it easy to predict how many units of goods a consumer will buy. As a reminder, consumers tend to buy goods until the marginal price (the cost of one more unit of the goods) is greater than the MU. If you know how much the goods being analyzed in the chart cost, the point where utility is maximized is the last row where MU is higher than the marginal cost. Let's say that the tickets in the example chart cost $3 each. In this case, utility is maximized when the consumer buys 4 tickets. The next ticket after this has an MU of $2, which is less than the marginal cost of $3. Note that utility isn't necessarily maximized when the MU starts to become negative. It's possible for goods to give some benefit to the consumer without being "worth it." For instance, the fifth ticket in the chart above still gives $2 worth of MU. This isn't a negative MU but it still decreases the total utility because it's not worth the cost. Once you have the three "core" columns above, it becomes easy to get more numerical data about the model situation the chart is analyzing. This is especially true if you're using a spreadsheet program such as Microsoft Excel that can do the math for you. Here are two types of data you may want to put in extra columns to the right of the three used above: Average Utility: The total utility in each row divided by the quantity of goods purchased. Consumer Surplus: The marginal utility in each row minus the product's marginal cost. It represents the "profit" in terms of utility the consumer gets from buying each product. It is also called "economic surplus."
Question: What is a summary of what this article is about?
Assign columns for quantity, total utility, and marginal utility. Look for a trend of diminishing returns. Determine Maximum Utility. Use the chart data to find additional information.

Problem: Article: There shouldn't be any chunks of biscuits left. Melt over a double boiler or in the microwave oven. Stir thoroughly to combine. If you are using dark chocolate, mix some milk while melting it. If needed, you can also add some sugar while melting it. The mixture shouldn't be liquid, but held together with a spongy dough-like consistency. Apply whipped cream to the top, if you want. Remove from the refrigerator to serve. If preferred, you can bring it back to room temperature for serving. Experiment with adding other nuts or dried fruits to find your favorite version.
Summary: Crush the plain sweet biscuits into a fine powder. Melt the chocolate, approximately 1/2 the amount of powdered biscuits. Add the melted chocolate to the powdered biscuits. Mix the melted chocolate and the powdered biscuits together with enough water to form a spongy dough. Shape the cake into a little mound on each plate. Decorate it with chopped raisins and almonds, as many as desired. Refrigerate the cake. Finished.

Many Internet service providers (ISPs) expressly forbid personal hosting unless you have a business plan, which often costs significantly more than a standard use plan. This shouldn't be an issue if your site only generates a few hits per month, but any kind of significant traffic will draw attention to your hosting. If your ISP prohibits home-hosting, either upgrade your plan to one that allows hosting or switch to a different ISP before you continue. Failing to heed your ISP's policy for home-hosting can result in anything from getting your Internet turned off to having to pay fines. In order to host a website, you must have a computer on and connected to the Internet 24 hours per day, seven days per week. This is easier to accomplish with a secondary, older computer than it is with your primary computer. Restarting your computer to update will occasionally be necessary. During these updates, your website will be inaccessible. Make sure that your computer is up-to-date with the latest operating system, security features, and drivers. Make sure you update your Windows computer or update your Mac computer before continuing. If your website's source code isn't already in a file on your computer, copy it from your web service's settings into a text document on your computer and save it as a PHP file. If the website's source code is stored on your computer, make sure you know where to find it. If you haven't yet programmed your website, you'll need to do so before continuing. MAMP is a free website hosting application that works on both Windows and Mac machines. To download MAMP: Go to https://www.mamp.info/en/. Click DOWNLOAD below the "Free" version.
