Its basic purpose is to explain and analyze prices and quantities traded in a competitive market. when you choose something, you have to pay the cost of not choosing the next best alternative. It spends $.5 million to conduct research and development programs for their new product. This example of Economics is the most basic concept of free-market economics that helps in determining the right price for a good or service.
