Answer:
<h2>The correct answer in this case is option C. or MU(c)/P(c)>MU(d)/P(d).</h2>
Explanation:
Under consumer equilibrium theory for two commodity model,a rational consumer maximizes his or her utility when the marginal utility(MU) obtained from consuming one good is equal to the same of the other.This is the fundamental essence of the Law of Equimarginal Utility in Economics.Now,in this case,the consumer will purchase more of good C than good D if the Marginal utility obtained from one unit of good C or MU(c)  for the money spend on consumption of good C or price of C,P(c) is greater than the marginal utility obtained from consuming 1 more unit of good D or MU(d) for money spend on purchase of good D or price of that particular unit of D or P(d).Therefore,since the marginal satisfaction compared to the amount of money spend for the consumer is higher for good C compared to the other or good D,it will increase the total utility level of the consumer from that particular consumption bundle or pattern.Hence,he or she will spend more on the consumption of good C than good D.
 
        
             
        
        
        
I would say that the market economy and westward expansion promoted the institution of slavery as in the new United States whereby in order to sell more say cotton at a cheap price (the market economy) then the landowners would employ slaves for cheap labour so as to extract maximum profit from their labour.
        
             
        
        
        
Answer:
Price - increase 
Domestic production- increase
Import- reduces 
Producer surplus- increase 
Explanation:
A tariff is a form of tax on import or export.
When a tariff is imposed on a good , the price of the good increases. 
As a result of the tariff , the amount of the goods imported falls as the imported good is now more expensive. The quantity produced by domestic producers increases as consumers would now start demanding for the domestic good. Tariffs are sometimes enacted to discourage importation and encourage domestic production. 
As a result of the price increase, producer surplus increases. The increase in price also increases output. The producer surplus is the difference between the price of a product and the least amount the producer is willing to sell his product.
