- A firm’s profit is given by the following function, which maps output q ≥ 0 onto profit (revenue minus cost). π(q) = 11q − (q 2 + 2q + 10) = −q 2 + 9q − 10, The firm is constrained by a quota such that output q cannot be greater than a value Q. (a) What is the domain of this profit function? 1 of 2 ECON10071/20071 - 2020/21 (b) Given this, what is (global) profit maximising output when (i) Q = 6, and when (ii) Q = 2.c) Assume that the market price for bagel services is 42 and store produces 30 units of the bagel. Calculate theprofit level. Is the store profit maximizing? Explain your answer. d) Go back to part c) and assume that there are 100 identical bagel store in the market. Determine the market supply curve. (You will obtain total market quantity, Q, as a function of price,P). Are elasticities of individual firm supply and market supply curves different? e) Given the market supply curve you have calculated in part d), now assume that market demand forhairdressers are given by Q=2900-50P. Find the equilibrium price and quantity in the market. Does the marketequilibrium correspond to long-run equilibrium? ExplainA price-taking firm in a competitive industry of a good that is continuously divisible (like sand) has a total cost function TC(Q) = 3.5Q^2 + 100Q + 500. The market price for the good is p = $240. a: Carefully write out this firm’s profit maximization problem, using the particulars of thisproblem. b: Give the marginal condition (equation) that characterizes the solution to this problem. Solvethis condition for the firm’s optimal quantity Q*. c: Calculate the firm’s maximized profit. d: On a graph with quantity on the horizontal axis, neatly plot the marginal revenue curve andmarginal cost curve. Show Q* on your graph. e: Label areas on your graph using a, b, c, etc. and indicate the areas that correspond to totalrevenue and variable cost.

Find the profit maximizing output level for this firm .b- What is the total revenue ?c- What is the total cost ?d- What is the profit earned by the firm ?e- Illustrate your answer by using a well-labeled graph .f- Denote the break even price level with Pb on the same graph .g- Denote the shut down price level with Ps on the same graph.h- Show the firm’s supply curve on the same graph .i- Does the firm function in short-run or long-run ? Why ?Demand and Supply equations of a particular market are as follows.Qd = 2100 – 7PQs = – 1200 + 5PWhere, Qd is the quantity demanded, Qs is the quantity supplied and P is the market price.

If the current market (equilibrium) price is $ 70, at what output level will the firm as a profit maximizer produce at? Say the market price rises to $ 100. At what output level (as a perfect competitor) will this produce at? How much profit is the firm making at a price of $90? Based on this calculation, do you expect firms to enter or leave this market? Say instead this firm is a monopoly. If the firm maximizes profit at an output level where marginal revenue equals $ 80, what output level will this be?If supply curve of firms in competitive market is P = 120 - 60Q1.
