Answer: D. At least every third audit
Explanation: According to the AICPA Professional Standards of auditing. Testing the operating effectiveness of controls that appear to function as they have in past years and on which the auditor wishes to rely upon in the current year must be carried out at least every 3rd Audit.
This is done if the auditor plans to use audit evidence from a prior audit about the operating 
effectiveness of specific controls. The auditor shall establish the continuing relevance of that 
evidence by obtaining audit evidence about whether changes in those controls have 
occurred subsequent to the previous audit.

Explanation:
Trade offs are something in which there are two things and we choose one of them according to our own preference or need. This is and should be our personal decision, but when Corporations and Governments decide on what to choose between two things, there would might be a negative impact on someone's life. He might feel controlled by the corporations and governments. For example, if corporations of CNG decides with the government that it is better for consumers to use CNG than Petrol in their cars, and lowers taxes on CNG and encourage consumers to shift towards CNG, then this trade off will have an impact of being controlled by the big giants. The choice should be of consumer's. The consumer should be the one who will trade off between things who are preferable for him. 
 
        
             
        
        
        
Answer:
$55.134
Explanation:
Given 
dividend paid on its stock = $8.25 
Duration is next 13 years
P0 = dividend on its stock × (PVIFA of return on this stock,years)
Remember PVIF = (1 - (1 + r)^-n)/r
Where PVIFA = present value interest factor of annuity
r = interest rate per period
n = number of periods
Therefore 
P0 = $8.25 × (PVIFA11.2%,13)
P0 = $55.134
