The MacDonald sells two popular packages of breakfast all day long: Mac A and Mac B. The sales of these products are not independent of each other (in economics, we call these substitutable products, because if the price of one increases, sales of the other will increase). The store wishes to establish a pricing policy to maximize revenue from these products. A study of price and sales data shows the following relationships between the quantity sold (Q) and prices (P ) of each model: QA = 20 - 0.62PA + 0.3PBQB = 29 + 0.1PA - 0.6PBi . Construct a model for the total revenue and implement it on a spreadsheet. b. Develop a two-way data table to estimate the optimal prices for each product in order to maximize the total revenue. c. Use "Solver" to find the optimal prices.

You sell two different goods: printers and toner cartridges. The price elasticity of demand for the printers is -3.4, and you earn a revenue of RM15,000 per month from the good. You earn a revenue of RM5,000 per month from the toner cartridges. The cross price elasticity of demand for both of the goods is -2.5. If you decide to decrease the price of the printers by 5%, calculate your new total revenues for both of the goods. [Anda menjual dua barang berbeza: pencetak dan kartrij toner. Keanjalan harga permintaan untuk pencetak adalah -3.4, dan anda memperoleh jumlah hasil sebanyak RM15,000 sebulan memperoleh jumlah hasil RM5,000 sebulan untuk kartrij toner. Keanjalan permintaan silang bagi kedua-dua barang adalah -2.5. Sekiranya anda membuat keputusan untuk menurunkan harga pencetak sebanyak 5%, hitung jumlah hasil baharu anda untuk kedua-dua barang tersebut.] (c) untuk barang tersebut. Anda

Suppose if the price of a good is $12, the quantity demanded is 50 units; when the price is $10, the quantity demanded is 100 units. Use the midpoint approach to compute the price elasticity of demand. Is demand at this point relatively responsive or relatively unresponsive to price changes?

Required information You are the manager of a firm that receives revenues of $20,000 per year from product X and $80,000 per year from product Y. The own price elasticity of demand for product X is −3 and the cross-price elasticity of demand between products Y and X is −1.6. Suppose you increase the price of good X by 2 percent.   Assume that the information about product X and product Y from the problem changed to the following:   Revenues per year from product X $ 15,000 Revenues per year from product Y $ 80,000 Own price elasticity of demand for product X   −3 Cross-price elasticity of demand between products X and Y   −1.4 Price increase of product X (percent)   3     Instruction: Update the data in your spreadsheet to the values above and enter the recomputed answer for the original question. Required: How much will your firm’s total revenues (revenues from both products) change? Change in revenues: ____________________

Suppose that your demand schedule for dvds is as follows: price quantity demanded (income = $10,000) quantity demanded (income = $12,000) $8 40 dvds 50 dvds 10 32 45 12 24 30 14 16 20 16 8 12 You mid point method to calculate your prize elasticity of demand

When the local pizza parlor prices pizzas at $12 each, it generally sells 7000 pizzas per month. If it lowers the price to $10, sales increase to 9000 pizzas per month. Given this information, we know that the price elasticity of demand for pizza is about 1.38, and an increase in price from $10 to $12 results in a decrease in total revenue. 0.72, and an increase in price from $10 to $12 results in an increase in total revenue. 0.72, and an increase in price from $10 to $12 results in a decrease in total revenue. 1.38, and an increase in price from $10 to $12 results in an increase in total revenue.

Suppose that for your demand schedule for pizza is as follows:a)Use the midpoint method to calculate your price elasticity of demand as the price of pizza increases from$8 to $10 if(i)your income is $20,000(ii)your income is $24,000.b)Calculate your income elasticity of demand as your income increases from$20,000 to$24,000(i)the price is $12 and (ii) the price is $16

The following graph shows two known points (X and Y) on a demand curve for oranges. (? 10 Y Demand 4 2 1 ㅜ 10 20 30 40 50 60 70 80 90 100 QUANTITY (Thousands of pounds of oranges) 0.05 0.2 0.25 According to the midpoint method, the price elasticity of demand for oranges between point X and point Y is approximately which suggests that the demand for oranges is between points X and Y. PRICE (Dollars per pound)

At Webs-R-Us, a website design company, the new manager has decided to increase the price of Webs-R-Us services by 45%. She estimates that the price elasticity of demand for Webs-R-Us is −0.70. The manager expects the number of websites designed to decrease by?

Using data on automobile purchases, P. McCarty (REStat 1996) estimated the following elasticities for compact cars sold in the United States. Own elasticity of demand Income Elasticity Cross Price* - 0.87 1.70 .82 * Responsiveness of demand for compact cars to changes in the price of other types of car models, such as luxury cars. а) What is the percent change in quantity demanded for compact cars given a 2 percent decrease in the price of compact cars? b) What is the percent change in demand for compact cars given a 2 percent decrease in the price of other car models? c) What is the percent change in demand for compact cars given a 2 percent decrease in income? d) Is demand for compact cars elastic or inelastic? Explain briefly. e) Would a decrease in the price of compact cars generate more or less revenue from the sale of compact cars? f) Are compact cars a normal or inferior good? Explain briefly. 5.
