A textbook publisher is in monopolistic competition. If the firm spends nothing on advertising, it can sell no books at $100 a book, but for each $10 cut in price, the quantity of books it can sell increases by 20 books a day. The firm's total fixed cost is $2,400 a day. Its average variable cost and marginal cost is a constant $20 per book. If the firm spends $1,200 a day on advertising, it can increase the quantity of books sold at each price by 50 percent. Compared to the situation if it does not advertise, if the firm advertises,the profit-maximizing price: A)falls by $10. B)rises by $5. C)rises by $10. D)does not change

Problem 3 A furniture maker builds and sells wooden benches. The demand function for the benches is given by the function p = 1600 -x where p is the price per bench and x is the number of benches sold. The furniture maker also knows that the fixed costs for the business are $20,000 and each bench costs $75 to make. Part a) Create a function that represents revenue as a function of the number of benches produced and create a function that represents the cost as a function of the number of benches produced. Make sure to label your input and output variables. Part b) How many benches should be produced and sold in order to maximize revenue? What price should the furniture maker sell them? (Make sure to show your work) Part c) How many benches should be produced and sold in order to maximize profit? What is the maximum profit? (Make sure to show your work)

Nathan runs a rare book store. Last year, he earned $35,000 in revenue and had explicit costs of $8,000. Nathan could have made $35,000 driving a boat in a water ski show and received an additional $5,000 if he had used the company's inputs in a different way. Calculate Nathan's economic profit. $

Giocattolo is a profit-maximizing firm producing toy cars, which it can produce and sell in its home country, Italy, and abroad in Spain. The average cost (AC) curve on the following graph represents Giocattolo's cost of producing toy cars within one factory, whether in Italy or in Spain. COST (Dollars per toy car) 20 18 16 14 12 10 8 4 2 0 0 10 20 30 40 50 60 70 80 QUANTITY (Thousands of toy cars) AC 90 100 Suppose that at the current market price of toy cars, the demand for Giocattolo's product is 10,000 toy cars per year in Italy and 20,000 toy cars per year in Spain. (Hint: Select each point on the previous graph to see its coordinates.) Based on Giocattolo's average cost curve, within one factory it can produce 20,000 toy cars at $ per toy car, and produce the total of 30,000 toy cars at $ per toy car. per car, produce 10,000 toy cars at

A friend has just started up her own business. Her firm asks you how much to charge for her product to maximize profits. The demand schedule for it is given by the first two columns in the table below; its total costs are given in the third column. For each level of output, you can calculate total revenue, marginal revenue, average cost, and marginal cost. The profit-maximizing level of output can be found at the point where TR - TC is greatest, or where MR = MC, (or the last quantity where MR is still greater than MC.) What is the profit-maximizing level of output for her product? 40 How much will she earn in profits? 80 Price     Quantity     TC                 TR?           MR?      MC? $25.00        0             $130  $24.00      10             $275 $23.00     20             $435 $22.50     30             $610 $22.00     40             $800 $21.60      50          $1,005 $21.20      60          $1,225

Calvin grows beautiful orchids. His total fixed cost is $90 a day, and his average variable cost is $2 a plant. Few people know about Calvin's Orchids and he is maximizing his profit by selling 18 orchids a day for $7 a plant. Calvin thinks that if he spends $20 a day on advertising, he can increase his market and sell 48 orchids a day for $7 a plant. If Calvin advertises will his average total cost increase or decrease at the quantity produced? If Calvin advertises and as a result he sells 48 orchids a day for $7 a plant, his O A. average total cost decreases if total cost decreases, and increases if total cost increases average total cost does not change at the quantity produced O B. O C. average total cost increases at the quantity produced O D. average total cost decreases at the quantity produced

Consider De Virtuose Cupcake, a cupcake shop in a competitive price-searcher market. The following graph shows its demand curve, marginal revenue (MR) curve, marginal cost (MC) curve, and average total cost (ATC) curve. Assume that the shop is operating in the short run. Place the black point (plus symbol) on the graph to indicate the profit-maximizing price and quantity. If the shop is making a profit, use the green rectangle (triangle symbols) to shade in the area representing its profit. If the shop is suffering a loss, use the purple rectangle (diamond symbols) to shade in the area representing its loss. PRICE (Dollars per cupcake) 4.00 3.50 3.00 2.50 2.00 1.50 1.00 0.50 0 MC 0 0.5 ATC 1.5 MR Demand 1.0 2.0 2.5 3.0 QUANTITY (Thousands of cupcakes) 3.5 4.0 At the profit-maximizing put and price, the shop's profit is equal to $ Given the profit-maximizing choice of output and price, there are + Profit Maximizing Outcome Profit Loss C.

The publisher of a magazine gives his staff the following information: Current price Current sales Current revenue Current total costs $2.00 per issue 150,000 copies per month $300,000 per month $450,000 per month He tells the staff, "Our costs are currently $150,000 more than our revenues each month. I propose to eliminate this problem by raising the price of the magazine to $3.00 per issue. This will result in our revenue being exactly equal to our cost." Refer to the table above, which of the following statements is correct? The publisher's analysis is correct only if the demand is elastic. The publisher's analysis is correct only if the demand is perfectly elastic. The publisher's analysis is correct only if the demand is unit elastic. The publisher's analysis is correct only if the demand is perfectly inelastic.
