Answer:
A. Money Market checking account
Explanation:
A money market account represents a savings account with some features of a checking account provided by a bank. Herein, a customer deposits money, and such funds are invested into money market instruments which are highly liquid, such as commercial papers, treasury bills, certificate of deposits, etc.
Such accounts provide debit card and checks and allow a certain number of withdrawals every month. The rate of interest offered under these accounts is usually higher than the ordinary savings account.
In the given case, the customer has $20,000 to invest and also requires immediate access to the funds to pay his bills. The best recommendation would be to deposit such funds to a money market checking account, which would provide him with access i.e liquidity, a higher rate of interest than on savings account and safety of investment.
It is noteworthy that all other options specified are not as liquid as money market checking account since, those alternatives either require considerable time in redeeming and selling or do not provide immediate access to funds.

Answer:
a) Gold = $1,380; Silver = $1,020
b) Gold = $1,300; Silver = $980
Explanation:
a) At first, with Qg = 60 and Qs = 270, the equilibrium prices for gold and silver are found by solving the following linear system:

Equilibrium price of gold is $1,380 and the price of silver is $1,020.
b) If the supply of gold increases to 120, since the goods are substitutes, there will be an increase in overall supply and the equilibrium price of gold and silver will decrease as follows:

Equilibrium price of gold is $1,300 and the price of silver is $980.
Answer:
C. the price effect would become a more significant consideration for each firm that makes automobiles.
Explanation:
The situation above is highly related to the topic about "supply" and "demand." If the nations of <em>Germany</em>,<em> Japan</em> and <em>the U.S.A</em>. prohibits the international trade in automobiles, this will result to a<u> surplus of automobile goods within the country.</u> Since these automobiles were meant to be sold abroad, the prohibition will<em> lower its international demand.</em> Such increase in supply will have a significant effect on the price of the automobiles. This is the reason why each firm should have to consider the situation's effect on the price of the automobiles and related goods.
So, this explains the answer.
Answer:
Companies have a corporate social responsibility towards their environment.
Explanation:
Corporate social responsibility implies that companies are expected to engage in industrial practices that would not result in harm to their environment. For example, the amount of carbon being released into the environment must be controlled as excessive release of carbon can be detrimental to health. It is also not right for waste to be discharged into the oceans because the health of the sea animals, the ocean itself and those who swim in it are at risk.
To promote sustainability, companies avoid practices that would eventually harm their environment. Abiding by these practices might take a longer route, but is eventually cost effective and beneficial.
