1. A producer has the total cost function C(q) = q2 + 2:; + 1600. (a) Solve for the marginal cost, average cost, and average variable cost functions. [b] 0n the same plot with quantity on the x-axis and price-per-unit on the y-axis, graph the three previously found functions. (c) Suppose that the xed costs for this producer were not sunk costs, and the producer could freely drop out of the market earning 0 total prots. Is there a threshold price for this producer; below which they would choose to produce 0 units? [d] Write down the supply function for this producer, assuming no sunk costs. (e) Does your previous answer change if these xed costs were in fact sunk costs? In this case, what is the threshold price
