Economic Systems & Markets

📋 What it is

Supply and demand set prices in a market; scarce, wanted things cost more.

🗣️ Coach says

A market is where buyers and sellers meet. Prices rise when lots of people want something scarce (high demand, low supply) and fall when there's plenty. This tug-of-war sets nearly every price you see.

🧠 Memory hook

High demand + low supply → higher price. Lots of supply → lower price. It's a tug-of-war.
