LET’S TRY ONE
At a price of 4 tokens, buyers demand 30 items and sellers supply 20. What shortage is shown at that price?
10 items
Demand exceeds supply by 30 − 20 = 10 items.
Learning steps & teaching tips
Interpret an invented market table while separating stated quantities from broader price predictions.
- Read the units and each price row.
- Compare supplied and demanded quantities within that row.
- Limit the conclusion to the stated market model and conditions.
Try it together
Create three price rows with quantities supplied and demanded. Locate a balanced row and calculate one shortage and one surplus.
Compare quantity supplied and demanded at the same listed price; do not mix rows.
