<h3>What is  
income?</h3>
Income is the consumption and saving opportunity gained by an entity over a given time period, which is usually expressed in monetary terms. Income is difficult to define conceptually, and definitions vary across fields.
Income is defined as the amount of money received by a person, group, or company over a specific time period. A salary of $70,000 per year is an example of income.
Income is money received by an individual or business in exchange for labor, the production of a good or service, or the investment of capital. Individuals typically earn money through wages or salaries, whereas businesses make money by selling goods or services for more than their cost of production.

Answer:
The correct answer is B) it eliminates all the unpopular items for the analysis to save time (and computing power).
Explanation:
Taking into account that the analysis of the association rule takes into account a group of products that are sold for being complementary or that are sold from the purchase of others without being complementary, in a retail business it will be relevant to consider the popularity of products to determine behavior or pattern. In this sense, the "a priori" algorithm determines a previous situation that is not taken into account to study similar behaviors between products.

True. To help travelers know what to expect researchers collect the prices of commodities. In most cases, you can find information before you travel somewhere to see the moeny you may spend on different things like hotel, transportation, food and activities. Researchers put this information up so people can look and get ideas about what they should expect to spend when traveling. 
 
        
             
        
        
        
Back in 2015, McDonald’s was struggling. In Europe, sales were down 1.4% across the previous 6 years; 3.3% down in the US and almost 10% down across Africa and the Middle East. There were a myriad of challenges to overcome. Rising expectations of customer experience, new standards of convenience, weak in-store technology, a sprawling menu, a PR-bruised brand and questionable ingredients to name but a few.
McDonald’s are the original fast-food innovators; creating a level of standardisation that is quite frankly, remarkable. Buy a Big Mac in Beijing and it’ll taste the same as in Stratford-Upon Avon.
So when you’ve optimised product delivery, supply chain and flavour experience to such an incredible degree — how do you increase bottom line growth? It’s not going to come from making the Big Mac cheaper to produce — you’ve already turned those stones over (multiple times).
The answer of course, is to drive purchase frequency and increase margins through new products. 
Numerous studies have shown that no matter what options are available, people tend to stick with the default options and choices they’ve made habitually. This is even more true when someone faces a broad selection of choices. We try to mitigate the risk of buyers remorse by sticking with the choices we know are ‘safe’.
McDonald’s has a uniquely pervasive presence in modern life with many of us having developed a pattern of ordering behaviour over the course of our lives (from Happy Meals to hangover cures). This creates a unique, and less cited, challenge for McDonald’s’ reinvention: how do you break people out of the default buying behaviours they’ve developed over decades?
In its simplest sense, the new format is designed to improve customer experience, which will in turn drive frequency and a shift in buying behaviour (for some) towards higher margin items. The most important shift in buying patterns is to drive reappraisal of the Signature range to make sure they maximise potential spend from those customers who can afford, and want, a more premium experience.
