Suppose Dan’s cost of making pizzas is C(Q) = 4Q + (Q2/40), and his marginal cost is MC = 4 + (Q/20). Dan is a price taker. (a) What is Dan’s supply function? (b) What is Dan’s supply function if he has an avoidable fixed cost of $10? [HINT: Recall that Dan will not supply anything unless P > min AC(Q). So, as a first step, you need to find AC(Q) from C(Q). In part (a), finding min AC(Q) is easy and you should be able to do so just by looking at the formula for AC (Q). For part (b), you can find the minimum of AC by using the fact that AC(Q) = MC(Q) at the minimum point of AC.]
