Quizplus · Accepted Answer

Consumer surplus is the area between the demand curve (marginal social benefit) and the price level, up to the quantity consumed. When the quantity decreases from 6 to 3 and the price increases from $3 to $4, the consumer surplus decreases by the area of the trapezoid formed between quantities 3 and 6 and prices $3 and $4. This area is calculated as [(3+4)/2] * (6-3) = 3.5 * 3 = $10.5. However, without the initial and final consumer surplus values or a graph, we cannot directly calculate the change in consumer surplus. The correct answer is inferred based on the given options and the understanding that consumer surplus decreases when quantity decreases and price increases, indicating a loss greater than the smallest values provided in the options but based on the information provided, the exact calculation cannot be directly determined from the question as it stands. The choice is based on the understanding of how consumer surplus is affected by changes in price and quantity, but the explanation mistakenly assumed specific calculations without visible data or a figure. The correct approach to determine the exact change in consumer surplus would require more information or a graphical representation.
