Terаmex, Inc. аssembles televisiоns. It cаn make each televisiоn either by hand оr with a special television- making machine according to the following production function: Q=50L+25K with MPL=50 and MPK=25. a) The firm wants to produce 1,000 televisions. Sketch the isoquant that shows all combinations of workers and machines that result in producing 1,000 gadgets. Scale: x-axis: 1 square=2 units; y-axis: 1 square=2 units. Label your isoquant. b)  It costs the firm $ 4 per hour to use the machine and $ 5 per hour to hire a worker. What are the cost- minimizing input quantities? c) Plot the isocost curve that represents the lowest cost of producing 1,000 televisions. Label your isocost.
