Supply



How much a certain good
is available to consumers.
As price increases…supply

Demand

they need or want at a price they can afford.

profit.
•

–
Shows how much of the
product that sellers are willing
to sell at various price levels.
Demand
•
Demand curve (demand
schedule)
–
Shows how much of the
product buyers are willing to
purchase at various price levels.
Price

Equilibrium (market) price
The point at which the supply
and demand curves meet.
– The price at which producers
are willing to sell their products
and the price at which

Using pictures from the magazines and what you just
learned create a collage of complimentary and
