Answer:
The number of CDs = 111.36
The number of movie videos = 242.72
N/B: I choose not to round up the answers.
Explanation:
The method used is the Lagrangian method. Basically, the optimization problem we are trying to solve is the utility function 
subject to the constraint
.
So the optimization problem(Lagrangian) is
,
where 
is a constant called the Lagrange multiplier.
To find the optimal consumption, we need to maximize the Lagrangian with respect to the variables 
. This we do by differentiating 
with respect to each variable and then equate to 0.
Equate (1) and (2), to get 
and substitute into (3) to get 
. Substituting into 
to get the corresponding value of 
.
If the Fed conducts open-market purchases, the money supply increases and aggregate demand shifts right.
Answer: Option B
<u>Explanation:</u>
With the Fed conducting an open market purchase, the people will sell of the securities that they possess. In return they will get money from the fed for the purchases that it makes. With the increase in the supply of money in the economy, there will be more demand by the people in the economy.
Therefore the aggregate demand curve will shift to the right direction showing more demand of the goods and services by the people in the economy.
Answer:
The correct answer is: C. larger decrease in total risk.
Explanation:
The risk of an investment portfolio refers to the possibilities of obtaining the return, profit or profit you expect. Every investment involves a risk, and the more you can earn, the greater the risk. If you put your money on a fixed term, the risk is minimal, but it hardly gives you an interest even less than inflation. If you invest in the forex market, for example, you can earn a lot of money, but also the risk (that you do not achieve and even that you lose what you invested) is much greater. Every investor knows that he must assume some risk, because it is something inherent in the investment.
Answer:
A business owner pays for rent and equipment at their office ⇒ FIXED COSTs since the amount of rent paid should be the same year after year
An airline considers the costs of serving food and beverages to its passengers ⇒ VARIABLE COSTS since the cost of serving food will increase as the number of passengers increase, or will decrease if the number of passengers decrease
A company considers the costs it pays to its employees ⇒ VARIABLE COSTS since the number of employee can vary and the number of hours worked can also vary
A clothing manufacturer buys new machines for its factory ⇒ FIXED COSTS since the machines are depreciated at a predetermined rate that doesn't depend on the factory's output
Answer: born global
Explanation:
An organization that is global within two years of its inception with a major focus on foreign markets rather than its domestic market can be said to be born global.
Since the day such organization is established, they seek to gain competitive advantage over their rivals by using latest technologies and selling their products in different countries.
