Information for questions 10-12 A firm’s short-run total cost function is given by C=550 + 300 Q + 10 Q2. Capital is the only input that is fixed in the short run, that is, it cannot be changed in the short run. Labor, on the other hand, is variable, and can be changed in the short run. The rental rate is $25 per unit of capital, the wage is $50 per unit of labor. For this group, answers within 1% of the correct answer are accepted, so carry several decimals in your calculations. Enter 0 if the question cannot be answered with the information provided.   Suppose that the answer to the previous question was Q=12.56. How much is the firm’s minimum Average Cost?

Information for questions 20-28 The following figure shows the cost curves for a firm in a perfectly competitive market. The curves depicted are marginal cost (MC), average cost (AC), and average variable cost (AVC). Market demand is given by Q=3500 – 5 x p. For the first four questions in this group (20-23, not all in the Canvas version), the firm is operating in the short run, with a market price is $50. For the numeric questions, only the exact answer is accepted, so make sure to double check your reasoning. You can get exact answers with the usual convention that lines cross grid points, and each other, where they seem to cross. Enter 0, if the question cannot be answered at all with the information provided.   By looking at the figure, which of the following best describes the firm’s decision on whether to shut down? At a market price of $50…
