Consider the data in the table below when you answer this question. (As the table suggests, the demand curve for this continuous good is a straight line and so is the supply curve. Use that information and the geometric method for calculating surplus.)

Colorado. The Mead market price of a motor scooter is given by the horizontal black line at $60. Each rectangle you can place on the following graph corresponds to a particular buyer in this market: orange (square symbols) for Bob, green (triangle symbols) for Cho, purple (diamond symbols) for Eric, tan (dash symbols) for Ginny, and blue (circle symbols) for Kenji. Use the rectangles to shade the areas representing consumer surplus for each person who is willing and able to purchase a motor scooter at a market price of $60. (Note: If a person will not purchase a motor scooter at the market price, indicate this by leaving his or her rectangle in its original position on the palette.) ?
