Try a sample
At a fixed price, an updated table shows demand increasing from 20 to 35 while supply remains 20. What changed in the listed quantities?
- Excess demand increased by 15 items.
- Demand fell by 15 items.
- Both quantities remained equal.
- Supply increased by 15 items.

Excess demand increased by 15 items.
Demand rose 15 while supply was unchanged.
A little hint: Compare quantity supplied and demanded at the same listed price; do not mix rows.
