Answer:
 I, II, and III are all correct and part of this model
Explanation:
The CAPM model or Capital Asset Pricing Model indicates the relationship between the amount of risk and the expected profit for a certain investment. This model holds many assumptions, which from the ones provided we can say that assumptions I, II, and III are all correct and part of this model. The only assumption that is not correct is IV, since the level of risk aversion that each investor has depends on how much they know about their investment.

<span>Time and interest rates are directly related to one another. When paying a loan that accures interest, the longer it takes for you to pay the loan back, the more interest you are going to pay on that loan. Over time, the interest adds up and can be a large sum of money, if you want to pay a lower amount of interest, it is often beneficial to pay off the loan in a quicker amount of time. </span>
        
                    
             
        
        
        
Answer:
The correct answer ise. do nothing and leave prices unchanged.
Explanation:
It has been observed that many oligopolistic industries exhibit an appreciable degree of price rigidity or stability. In other words, in many oligopolistic industries prices remain sticky or inflexible, that is, there is no tendency for oligopolists to change the price even if economic conditions undergo a change.
There have been many explanations of this price rigidity in the oligopoly and the most popular explanation is the so-called crooked demand curve hypothesis. The crooked demand curve hypothesis was presented independently by Paul M. Sweezy, an American economist, and by Hall and Hitch, Oxford economists.
It is to explain the price and production under oligopoly with product differentiation, that economists often use the hypothesis of the crooked demand curve. This is because when products under oligopoly differ, it is unlikely that when a company increases its price, all customers abandon it because some customers are intimately linked to it due to product differentiation.
As a result, the demand curve facing a company under differentiated oligopoly is not perfectly elastic. On the other hand, under the oligopoly without product differentiation, when a company increases its price, all its customers leave it, so that the demand curve faced by an oligopolist that produces a homogeneous product can be perfectly elastic.
 
        
             
        
        
        
Answer:
The demand for beer is inelastic
Explanation:
Price Elasticity of Demand (PED) is the measure of responsiveness of the demand of a consumer to a product to a change in the price of the product. The formula is percentage change in quantity demanded divided by percentage change in price.
A PED of greater than 1 is elastic, meaning that the demand for a product is sensitive to the very small change in price.
A PED of less than 1 is said to be inelastic, which implies that there is no significant change in the quantity demanded when the price changes. In our example, the PED is inelastic because:

since 0.25 is less than 1, PED is inelastic
Finally, if the ratio of the percentage changes in both quantities demanded and price equals 1, it is said to be unit elastic. This means that there is a proportionate change in quantity demanded with a change in price.
 
        
             
        
        
        
Answer:
Option 2 should be selected
Explanation:
Using a rational approach which option most benefit and have a minimum cost. We will use the break-even level here to decide which option should be selected.
Option 1
Price per call = $30
Variable cost per call = $18
Contribution = Sales  - Variable cost = $30 - $18 = $12
Fixed Cost = $15,000
Break-even point = Fixed cost / Contribution per call = $15,000 / $12 = 1,250 calls
Option 2
Price per call = $30
Variable cost per call = $18 + ( $30 x 10% ) = $18 + $3 = $21
Contribution = Sales  - Variable cost = $30 - $21 = $9
Fixed Cost = $9,000
Break-even point = Fixed cost / Contribution per call = $9,000 / $9 = 1,000 calls
Difference  = 1,250 calls - 1,000 calls = 250 calls
Option 2  is better option because it take 250 less calls to reach at break-even in the month. It should be selected.
