1. Profit maximization and loss minimization BYOB is a monopolist in beer production and distribution in the imaginary economy of Hopsville. Suppose that BYOB cannot price discriminate; that is, it sells its beer at the same price per can to all customers. The following graph shows the marginal cost (MC), marginal revenue (MR), average total cost (ATC), and demand (D) for beer in this market. Place the black point (plus symbol) on the graph to indicate the profit-maximizing price and quantity for BYOB. If BYOB is making a profit, use the green rectangle (triangle symbols) to shade in the area representing its profit. On the other hand, if BYOB is suffering a loss, use the purple rectangle (diamond symbols) to shade in the area representing its loss. 4.00 3.50 Monopoly Outcome 3.00 2.50 Profit ATC 2.00 1.50 Los 1.00 MC 0.50 D MR 0.5 1.0 1.5 2.0 2.5 3.0 3.5 4.0 QUANTITY (Thousands of cans of beer) Suppose that BYOB charges $2.50 per can.

A firm has a linear demand function for its product. When the price of the product isSh.220, the quantity demanded is 40 units. When the price increases to Sh.240, thequantity demanded becomes 30 units. In addition, the firm’s marginal cost function isgiven by:MC = 40q – 2q2 + 2Fixed cost = Sh.5 millionWhere q = quantity demanded, MC = marginal cost (Sh. million)Evaluate the level of output that maximizes profits.
At 130 units of output, marginal revenue is $8, marginal cost is $8, and average cost is $5. If consumers demand 130 units of output when the price is $9, what is the expected profit? Provide your answer below:

6. esc A company sells one of its products for $42 each. The monthly fixed costs are $2700. The marginal cost of the product is $10. Let q=quantity and C(q) = cost. a) Express the total monthly costs, C, as a function of q, the quantity produced each month. C(q) = 9= :0: 21 O Express the total monthly revenue, R, as a function of the quantity, q, sold each month. R(q) = c) Find the quantity, q, produced and sold each month at which this company will break even. Round your answer to a whole number. F1 50,252 8.

On the occasion of summer vacation, a student plans to open a milk tea shop. Before deciding to open a store, she wants to find out how profits fluctuate with fluctuations in selling prices and costs per unit of product. The selling price per cup of milk tea can range from VND 20,000.00 to VND 30,000.00 (the level of change is VND 1,000.00 each time) and the cost to make a cup of milk tea can range from VND 13,000.00 to VND 17,000.00 (the level of change is VND 500 each time). Knowing that the initial fixed cost is VND 24,000,000.00 and the number of cups of milk tea sold (Demand) depends on the selling price according to the formula: Demand = 24000 - 0.5 * Unit Price Use the two-dimensional sensitivity analysis to answer the following questions: a) What is the profit if the selling price is 23,000.00 VND and the cost per unit is 15,000.00 VND? b) How will profit change with each increase in cost of a product unit by VND 500.00 with a constant selling price of VND 25,000.00? c) What is…
