Why does a coffee cost $3.50 — not $1, not $10? Nobody sets that price alone. Buyers and sellers set it together, and you're about to see how.

In this lesson you'll:

• build a demand curve from 24 real buyers,
• build a supply curve from 24 cups of coffee,
• find the market price — and see why markets drift towards it,
• predict what news, bad weather and price rules do to a market.

About 45 minutes · no maths beyond reading a chart · your phone or laptop.
