I need help.

I don't know how to reply to this paragraph. Can someone help me to reply to this paragraph in economics terms? Thank you

"Core Principles of Economics". It suggests that the foundation of economics remains unchanged whether it pertains to microeconomic or macroeconomics. What I found most interesting about the chapter is the idea that economics can be used as a method of thinking in everyday decisions rather than only being applied to businesses and accounting. For example, the examples presented in the text such as whether a $3 cup of coffee is worth its price(cost-benefit principle) if continuing one's education outweighs its alternative (opportunity cost principle), and how one more hour of studying affects how one's other time is spent (interdependence principle). All these examples demonstrate how the principles of economics are used to make rational decisions. The significance of everyday applications of economics is that it allows students to think more broadly about economics and apply its principles to a wide range of issues. More importantly, it prepares students to eventually apply economic thinking to more abstract and complex problems by familiarizing and cementing us with the core principles.
