Using the MC curve, find out how much output in total is delivered to the market at each price (you only need to consider prices equal to the MC values above). Now assume that the market demand curve is given by p 305.5Q, where p is the market price. For purposes of this problem, it is helpful to "invert" the demand curve, writing Q in terms of p.

Consider the perfectly competitive market for titanium. Assume that, regardless of how many firms are in the industry, every firm in the industry is identical and faces the marginal cost ( MCMC ), average total cost ( ATCATC ), and average variable cost ( AVCAVC ) curves shown on the following graph
The following graph illustrates the demand and marginal revenue curve (D-MR) of a perfectly competitive firm. Suppose that when the firm produces 40 units, its average variable cost equals $65 per unit and its average total cost equals $80 per unit. Use the green rectangle (triangle symbols) to plot the total cost of producing 40 units. Next, use the grey rectangle (star symbols) to plot the total variable cost of producing 40 units. Then, use the tan rectangle (dash symbols) to plot the total revenue at 40 units. Finally, use the purple rectangle (diamond symbols) to plot the profit or loss at 40 units.

Consider the market for ice cream. Suppose that this market is perfectly competitive. The cost structure of the typical ice cream producer is as follows. Average total cost is equal to 50 1 1 ATC(Q) +÷Q, average variable cost is equal to AVC(Q) =;Q, and marginal cost is equal to 2 MC(Q) = Q. Now, suppose that a new scientific study comes out that shows that soil pollution from rock salt (a key input for making ice cream) is extremely hazardous to human health. In response, the government decides to impose harsh re-zoning restrictions on any land once used for making ice cream. This reduces the market rent for land used to make ice cream, which in turn lowers the opportunity cost of operating an ice cream factory. This reduction in the opportunity cost of capital causes the total fixed cost of ice cream production to fall to 32, but there is no change to variable cost. Give formulas for the typical ice cream producer's new average total cost curve ATC(Q) and marginal cost curve MC(Q).

A firm has a cost function of C = 1000+20Q + 1/10Q2 and has a demand function as shown in the graph below: 100 90 80 70 70 60 60 50 40 30 20 10 0 10 20 30 40 50 60 70 80 90 100 Quantity (Q) -P (demand) a) Estimate the firm's demand function.

Assume that a competitive firm has the total cost function: TC=1q3−40q2+820q+1900TC=1q3-40q2+820q+1900 Suppose the price of the firm's output (sold in integer units) is $650 per unit. Using tables (but not calculus) to find a solution, what is the total profit at the optimal output level? Please specify your answer as an integer.
In competitive markets, there are many small firms with each firm unable to influence the market price. Suppose company ABX operates in the wheat market. The company produces and markets wheats at a Price = $20 per container. The firm’s total costs are given as: TC = 50 +2Q + 3Q2 What is the firm’s demand curve? Show it on a graph and label the axes showing P and Q
If there were 60 firms in this market, the short-run equilibrium price of titanium would be $________ per kilogram. At that price, firms in this industry would (earn a positive profit, shut down, earn zero profit, operate at a loss). Therefore, in the long run, firms would ( enter, exit, neither enter nor exit) the titanium market. Because you know that perfectly competitive firms earn (positive, zero, negative) economic profit in the long run, you know the long-run equilibrium price must be $_______ per kilogram. From the graph, you can see that this means there will be (20, 40, 60) firms operating in the titanium industry in long-run equilibrium.
The following diagram shows the market demand for steel. Use the orange points (square symbol) to plot the short-run industry supply curve when there are 20 firms in the market. (Hint: You can disregard the portion of the supply curve that corresponds to prices where there is no output since this is the industry supply curve.) Next, use the purple points (diamond symbol) to plot the short-run industry supply curve when there are 40 firms. Finally, use the green points (triangle symbol) to plot the short-run industry supply curve when there are 60 firms. PRICE (Dollars per ton) 80 72 Supply (20 firms) 64 58 Demand 48 Supply (40 firms) 40 32 2 24 16 8 ° 0 120 240 360 480 600 720 840 960 1080 1200 QUANTITY OF OUTPUT (Thousands of tons) Supply (60 firms) ? If there were 60 firms in this market, the short-run equilibrium price of steel would be $ Therefore, in the long run, firms would Because you know that perfectly competitive firms earn be $ per ton. At that price, firms in this industry…
Suppose that the perfectly competitive for market for milk is made up of identical firms with long-run total cost functions given by: TC = 4q³-24 q² + 40 q Where, q = litres of milk.
