When making decisions, it is essential to consider the costs and benefits involved. Cost-benefit analysis is a tool used in a variety of real-life situations. For example, in healthcare, it can be used to compare the costs of different treatments with their potential benefits. In environmental planning, it can help assess the costs of pollution control measures against the benefits of a cleaner environment. Businesses also use cost-benefit analysis to evaluate investment projects by weighing the expected returns against the initial costs. This analysis provides a systematic approach that assists in making informed choices and maximizing outcomes in various fields. Ultimately, cost-benefit analysis enables individuals and organizations to make rational decisions based on a thorough assessment of the pros and cons.
