Question

how is a decrease in supply represented on the supply curve? a new curve is shifted outward and to the right of the original. there is a movement downward and along the curve. a new curve is shifted inward and to the left of the original. there is a movement upward and along the curve.

Explanation:

A decrease in supply means producers offer less of a good at every price level. This is represented by a leftward (inward) shift of the entire supply curve, not a movement along the curve (which is caused by price changes, not supply changes). Shifting right/outward is an increase in supply, while movements along the curve reflect quantity supply changes.

Answer:

C. A new curve is shifted inward and to the left of the original.
