The daily production of glintstone crystals requires workers (L) and machines (K). The production function is given by: Q = 5L'5K where Q is the quantity of glintstones mined. The wage for workers is w=30 and the rental rate of machines is r=15. Initially, the quantity of machines is xed at K=32. The rm wants to produce 1280 glintstones. What are the returns to scale of this production function? 0 A. Increasing O B. Decreasing O c. Constant Suppose the rm wants to mine 1280 glintstones. In the short run. how many workers would it need to employ? cm What is the short-run cost of mining 1280 glintstones? Cost=l:| Now suppose that the rm is looking to the long run. If the rm plans to continue producing 1280 glintstones, how much labor and capital will it employ? L=|:| K=|:| How much does it cost to produce 1280 glintstones in the long run? Cost= I]
