You work for an airline company as a ticket operations manager at a major airport. Your unit is responsible for issuing boarding passes to 30,000 customers per day. Currently you employ 80 customer service representatives (CSRs) and 10 electronic ticketing machines to meet this demand. Each CSR is paid wages and fringe benefits of $150/day. It also costs you $150/day to lease each machine (price includes installation, software support, and servicing). A computer vendor has offered to lease you additional electronic ticketing machines at this price. You estimate that by leasing 10 more machines you can meet your service requirements with 30 fewer CSRs. Should you lease the additional machines or continue to service your customers with your current input mix
Plot the input combinations in the table on a graph that contains CSRs on the vertical axis and machines on the horizontal axis. Connect the points by lines to approximate an isoquant as pictured in Figure 5.6. Add the cost minimizing isocost curve to the graph (you can derive this line from the input prices and the total cost of the low-cost input combination). How do the slopes of the isocost curve and isoquant compare at the optimal input combination
