When a restaurant stays open for lunch service even though few customers patronize the restaurant for lunch,which of the following principles is (are)best demonstrated?

Quizplus · Accepted Answer

(i) The principle of opportunity cost is demonstrated because the restaurant could potentially use the resources (such as staff, utilities, and ingredients) used during lunch service for other more profitable ventures. 
(iii) The principle of cost-benefit analysis is demonstrated because the restaurant has weighed the costs of staying open for lunch (such as labor and utility expenses) against the potential benefits (such as attracting new customers or meeting the needs of current customers) and has determined that it is still worthwhile to offer the service. However, the principle of diminishing returns is not demonstrated since the statement doesn't mention any reduction in productivity or efficiency.
