<span>Symbolic interactionists believe that the social value of the elderly in America decreased when the economy shifted being agricultural to industrial.
This may be completely true - industrial era means more use of technology, and usually, the elderly aren't that keen on using new technology. This also means that they are less and less relevant when it comes to the social life in America which is always growing and developing.</span>
Answer: A. equal to marginal cost where it intersects the demand curve
Explanation:
In a pure competition, the market is efficient because it balances demand and supply and gives an equilibrium price that takes both of them into account.
In this market, the price is equal to the marginal revenue of a firm and the profit maximizing level of production is where the marginal revenue intersects the marginal cost.
The efficient level is therefore where price equals marginal cost. The same goes for a natural monopoly. If economic efficiency is to be achieved, the natural monopoly's price must equal the marginal cost at the equilibrium price.
Answer:
The citizen, however, does not have to pay because the police officer has a pre existing duty.
Explanation:
"Preexisting duty rule is a common-law rule of contract. It says that the rule that performance of an act by which a party is already contractually bound to perform does not constitute valid consideration for a new promise. In other words, a party's offer of a performance already required under an existing contract is an insufficient consideration for modification of the contract."
Then, the citizen doesn't have to pay because the police officer has an existing contract, and it's considered an insufficient consideration for modification of that contract.
