9) Suppose the supply of a good is perfectly elastic at a price of $15. The market demand curve for this good is linear, with zero quantity demanded at a price of $25. Given that the slope of this linear demand curve is -0.25, draw a supply and demand graph to illustrate the consumer and producer surplus that occurs when the market is in equilibrium.. Calculate the consumer surplus, producer surplus, and total surplus for this market. (5 points)
