If there is a decrease in supply (parallel shift of demand to the right) ,assuming a positively sloped supply curve and a negatively sloped demand curve,total surplus:

A) will increase.
B) will decrease.
C) will remain the same.
D) may change,but we can't tell how.

Positively Sloped

A line or curve on a graph that increases in value as it moves from left to right, indicating a direct relationship between two variables.
