different quantities of a good
at different prices
during a specific time period.

22
Q

Law of Supply

A

As the price of a good rises, the quantity supplied of the good rises, ceteris paribus. (And Vice versa).

23
Q

Supply curve

A

The graphical representation of the law of demand.

Why are most supply curves upward sloping

A

Law of diminishing marginal returns.

25
Q
