(a) A small manufacturing rm operates a production line that makes steel shafts that are used in oil drilling. The rm's total cost curve for shafts is given by Total Cost 2 15, 600 + 0.562 + 0.025422, where Q is the number of shafts produced annually. Steel shafts are ubiquitous, and this rm's shafts are indistinguishable from those of competitors. As a result, this rm is a price-taker. The rm's marginal cost is given by Marginal Cost 2 0.5 + 0.0562. What is this rm's supply curve
