b.

Answer to Problem 64E
Consumer surplus is
Explanation of Solution
Given information:
Graph that represents the systems of inequalities representing the consumer surplus and producer surplus for the given supply and demand equations:
Calculations:
From the graph, we can see that consumer surplus (CS) is the triangular region with height 50 units and base 250000 units.
Therefore,
Similarly, producer surplus (PS) is the triangular region with height 125 units and base 250000 units.
Therefore,
