Explanation:
Marginal beneficit and marginal cost are economic concepts. On the one hand, the marginal beneficit is defined as the added satisfaction a consumer gets from an additional unit of a good or service. On the other hand, the marginal cost is the change in total cost that results from making or producing one additional item.
The consumer could use these measurements to consider whether the cost is higher than the benefit when purchasing an item or getting a new service. Do they really need to buy an extra t-shirt when they already have enough of them? The benefit would be that they would get another t-shirt. In addition, as this is a new piece of clothing, it would probably be more in fashion than the old ones. However, the consumer would have to spend an amount of money that perhaps he had saved for another purpose and consequently would lack money for it. If he decided not to buy the t- shirt, he would have said amount of money to pay for his taxes or services. The same applies when it comes to the extra smoothie. The amount of money spent on the smoothie could be used to get something else and, by getting an extra one, you would feel fuller and perhaps would not eat a proper meal afterwards. You could also gain weight if the smoothie is not healthy, so in the end the cost is higher than the benefit.
Therefore, you could easily apply economic concepts, such as the ones described, in your everyday life so as to make decisions that leave you better off. By considering the cost associated with an extra purchase, you could start saving up money. Eventually, you could spend your savings to get a greater benefit. For instance, you could go on vacation without spending your salary and still comply with the payment of your taxes and services.
The geography of Southwest Asia opens up a space for a good connection between the countries and thus to create similar, if not same, cultural traits because of the absence of natural blockades between them, so the communication is easily manageable. Still, the region is dominated by deserts, so even though there's no big mountain ranges between them, it makes it difficult, apart from the coastal areas. Now even though the open terrain usually contributes to good relations, it occasionally causes problems as well, and this region is a perfect example of that, because lots of the countries are in very bad relations.
By protecting intellectual property, we made a specific invention could only be produced by the inventors alone.
Which means that the companies in other countries do not possess the right to produce it. This will increase the GDP of the country where the inventors came from
