Suppose there are three buyers (A, B, and C) in a competitive market with the marginal benefit (MB) schedules like those shown in the table below. Calculate the consumer surplus using the market demand curve. Assume that the market price is $10. Show that you get the same answer by adding the consumer surplus for all three buyers. How much does consumer surplus increase for the market as a whole and for each individual when the market price falls to $8?
