Answer:
Economy's marginal social benefit=$65
Explanation:
The economy's marginal social benefit can be calculated by getting the average of the individual marginal benefit.
This can be expressed as;
Economy's marginal social benefit=Sum of individual marginal benefit/Total number of individual's
where;
Sum of individual marginal benefit=John's marginal benefit+Nick's marginal benefit+Christina's marginal benefit=(80+50+65)=$195
Total number of individuals=3
replacing;
Economy's marginal social benefit=195/3=65
Economy's marginal social benefit=$65
 
        
             
        
        
        
Answer:
Sink-Cost Fallacy
Explanation:
According to my research on studies conducted by various behaviorists, I can say that based on the information provided within the question the mental bias that describes Les's behavior is called the Sink-Cost Fallacy. This fallacy/bias refers to when an individual relentlessly continues's a behavior solely because of the resources that they have invested, either being time, money, or effort. Which in this case since, Les invested money into the drink so he does not want to waste it even though it might make him sick.

Answer:
Project's WACC = 12.95%
Explanation:
The WACC or weighted average cost of capital is the cost of a firm's capital structure. The capital structure of a firm may contain one or all of the following components - debt, preferred stock, common stock. For a firm with two components in capital structure in form of debt and equity, the WACC is calculated as follows,
WACC = wD * rD * (1+tax rate)  +  wE* rE
Where,
- wD and wE are the weights of debt and equity in the total capital structure
- rD and rE are the cost of each component
- We multiply the cost of debt by 1 - tax rate to calculate the after tax cost of debt
We must first determine the weight of debt and equity in total capital structure.
A debt to equity ratio of 0.64 means 0.64 debt for every 1 dollar of equity. The total assets are made up of debt + equity. So, total assets are 0.64 + 1 = 1.64
Weight of debt = 0.64 / 1.64 = 16/41
Weight of equity = 1 / 1.64 = 25/41
WACC = 16/41 * 0.053  +  25/41 * 0.149
WACC = 0.1115 or 11.15%
The projects cost of capital is 1.8% more than the company's WACC.
So, the project's cost of capital is,
Project's WACC = 11.15% + 1.8%
Project's WACC = 12.95%
 
        
             
        
        
        
Answer:
Zach's annual opportunity cost of the financial capital(implicit + explicit)that has been invested in the business is $700.        
Explanation:
opportunity cost = 3%($10,000) +8%($5,000)
                            = $300 + $400
                            = $700
Therefore, Zach's annual opportunity cost of the financial capital(implicit + explicit)that has been invested in the business is $700.
