Elesha babysits on the weekends for extra money. Suppose that three neighbors with children are interested in paying Elesha to babysit their children. In particular, Dr. and Mrs. Brown would be willing to pay $30 to have Elesha babysit their children, Mrs. Smith would be willing to pay $29 for Elesha’s babysitting services, and Professor and Mrs. Jones would be willing to pay $21 to have her watch their children. If Elesha offers to babysit each set of children for an evening for $21, what will be consumer surplus, considering the three sets of children combined?
