12. How Consumer Surplus Relates to Values and Costs Aa Aa The following graph shows the market for wheat. The downward-sloping (blue) line represents demand, and the upward-sloping (orange) line represents supply. The market is perfectly competitive and currently in equilibrium at a price of 70 per tonne On the graph, use the green triangle (triangle symbols) to shade in the area representing consumer surplus Tool Tip: You can mouse over the shaded region on the graph to find its area PRICE (Euros per tonnel 100 CS 80 60 40 20 10 QUANTITY (Thousands of tonnes Help Clear AlL At a price of 70, all consumers who choose to buy a tonne of wheat value them at information, consumer surplus in this market is .
