Answer:
A) They would be indifferent, as Sally's income net of costs equals $25,000.
Explanation:
Sally's economic profit = accounting profit - opportunity costs
- accounting profit = $12,000
- opportunity costs = $25,000 - $15,000 in lost salaries + $2,000 (lost investment revenue) = $12,000
economic profit = $12,000 - $12,000 = $0
Since the economic profit is $0, Sally should be indifferent between running her own business or working for someone else. 
 
        
             
        
        
        
Answer: The marginal utility is 2
Explanation:
Utility is the satisfaction derived from the consumption of a particular commodity. Total utility is the total satisfaction derived from the consumption of a particular commodity. Marginal utility is the extra satisfaction that a consumer gets from consuming a product. Utility is measured in utils.
Marginal utility increases with an extra consumption of a good at first but later it begins to reduce as the extra good consumed doesn't really have give the consumer enough satisfaction anymore. 
Regarding the question, eating 5 hotdogs gives 40 utils and eating 6 hotdogs gives 42 utils. 
The marginal utility is the extra utils which will be 42-40 which gives 2 utils.
