  1. 1

    How does price affect supply?

    As price increases, quantity supplied typically rises as production becomes more profitable; lower prices reduce supply.

  2. 2

    How do costs of production influence supply?

    Model answer

    Higher production costs reduce supply as it becomes less profitable; lower costs increase supply.

  3. 3

    How does technology affect supply?

    Model answer

    Improved technology increases supply by making production more efficient and reducing costs.

    How does the number of suppliers influence supply?

    Model answer

    More suppliers in a market increase total supply; fewer suppliers reduce it.

    Model answer

    Taxes increase costs and reduce supply; subsidies reduce costs and increase supply.
