Answer:
20 is the socially optimal number
Explanation:
In this question, we are asked to calculate the socially optimal number of clean streets given the marginal cost of cleaning them.
To solve this problem, we employ a mathematical approach as follows:
Market demand = Sum of Individual demand
Magaret demand = p = (50-Q)/2 = 25-0.5Q
Thomas demand = P = 40-Q
Market demand = 25-0.5Q + 40-Q = 65-1.5Q
MC = 35
Socially optimal number = MC = Market demand
35 = 65-1.5Q
30 = 1.5Q
Q = 20
In any field of study, people always start with the ideal scenario in order to eliminate external factors that could only add complexities. Then, when we fully understand the concepts, the calculations gradually evolve to more complex ones to cater to realistic problems.
The basic assumptions that economists do are the following
1. People always have preferences on a set of outcomes and this can be determined through the quantity and quality of their value
2. People always maximize utility or the satisfaction you get out of buying and using the product.
3. Businesses always maximize profit.
Answer:
Demographic factor is the correct option.
Explanation:
The demographic variables can affect our business. Demography can be used to know the product's performance and the buying behavior of consumers. It helps companies to identify the key customers. After the identification, they can target these customers with customized advertisements and promotions. It helps the company to maximize its sales.
Income is one demographic variable. A person's income decides his buying habits. People having towards the low end of the salary band tend to buy less expensive products. While those with high salaries tend to buy expensive products. It is an example of a demographic factor.
Starbucks uses a product development strategy when it announced the release of the single-serve coffee maker in its outlets at the United States. This is because they plan to offer a new product, which is an improvement to the existing coffee maker devices in the U.S. market.
