Answer:
A is the correct answer.
Explanation:
Oligopoly is the market form in which a small number of large sellers dominate. It results in the reduction of the competition and leads to higher prices for consumers. they have their market structure. In oligopoly each firm stays aware of others, hence their decisions influence others and vice versa. The developed economies are dominated by Oligopolies. For example, if the total market share of the American telecom companies (Verizon wireless, AT and T and T mobile ) is combined, it comes out to be more than ninety percent.
C. John Jacob Astor.
The American business that had a monopoly on the fur trade in the far west was founded by John Jacob Astor.
The business was called American Fur Company. Since it was founded, the company grew to monopolize the fur trade in the United States by 1830. It became one of the largest and wealthiest businesses in the United States.
C = 50 + 0.8Y is the consumption function that is consistent with the provided data. The MPC is determined by subtracting the change in consumption from the change in disposable income, which equals 160/200, or 0.8.
Marginal propensity calculation.
$200 billion less $0 billion equals $200 billion in changes to disposable income.
Consumption change equals $210 minus $50, or $160 billion.
MPC = Change in Consumption/Change in Disposable Income, which equals $160 billion/$200 billion and is equal to 0.8.
There is a 0.8 marginal tendency to consume.
Step 2
This is how consumption function is defined.
C = a + bY
Where,
a = Consumption at zero income level
b = MPC
In given case,
$50 billion would be consumed at a level of income zero.
MPC is 0.8
So,
C = 50 + 0.8Y is the consumption function that matches the provided data.

Answer:
c. firms are free to enter and exit the market.
Explanation:
A monopolistically competitive market is a market in which there are a lot of organizations that sell products that are similar and it tends to be easy to enter and leave the industry. Because it is easy for a company to enter the market and there is a lot of competition, in the long run the economic profit is zero. According to this, the answer is that in the long run, profits in a monopolistically competitive market are zero because firms are free to enter and exit the market.
The other options are not right because a monopolistically competitive market has zero profits because of its low entry barriers and amount of competitors not because of government regulations or an illegal agreement between organizations to control competition. Also, in a monopolistically competitive market the products are similar.
