Three ancient poems in the lower Chinese language of the fifth grade of primary school

The ancient poems in the second volume of the Chinese texts of the fifth grade are: "Shepherd Boy", "Boat Over Anren", "Qingping Le Village Residence".

Consider the problems faced by two businesses – Post and Kellogg. Each company will have a new cereal on the market for $3 per box of sales**. To keep things simple, let's assume that the marginal cost of producing cereal is zero, and therefore, $3 is all profit.

Every company knows that if $10 million is spent on advertising, 1 million consumers can try out their new cereal. And, every company knows that if consumers like cereal, they don't buy it once, they buy it many times.

Let's start with Post's decision. According to market research, Post knows that its cereal taste is average. While advertising can get 1 million consumers to buy a box each, consumers quickly learn that cereal isn't so good and stop buying it.

Post decided that it wasn't worth paying $10 million in advertising and only getting $3 million in sales. Therefore, it is not intended to advertise. It makes the chef go back to the kitchen for another flavor.

Kellogg, on the other hand, knows that its cereal is fantastic. Everyone who tried it would buy a box every month for the second year. As a result, $10 million in advertising dollars can generate $36 million in sales.

Here, advertising is profitable because consumers buy Kellogg's good products repeatedly. Therefore, Kellogg chose to advertise.

Now that we've considered the behavior of two businesses, let's consider the behavior of consumers. We start by asserting that consumers tend to try the new cereal they see from the advertisement. But is this behavior rational?

Will consumers try new cereal just because the seller chooses to advertise?

The details are as follows:
