In the market for delivery truck drivers, L_S = -45 + 5W and L_D =

180 - 10W, where L = number of workers and W = wage in dollars per hour. In the market for librarians, LS = -15 + 5W and L_D = 190 - 10W. Find the equilibrium wage and employment level in each occupation, and explain what will happen if a comparable-worth law mandates that the librarians’ wage be increased to equal the delivery truck drivers’ wage. Use a graph.
