Limited resources mean we can’t have everything we want, so we have to make choices about how to use what we have. This idea is scarcity, and it leads to deciding what to prioritize. When you pick one option, you give up another possibility—the next-best use of that resource. That trade-off is called the opportunity cost. For example, if you have a limited amount of money and must choose between a book and a movie, choosing the book means you forgo the movie experience. If you spend an hour on homework, you have less time for friends or fun—those are your trade-offs. These trade-offs show why people and societies must continually weigh costs and benefits to decide how to allocate resources like money, time, and materials. The concept helps explain everyday decisions and larger economic choices, from personal budgets to government spending.
