The Camera Shop sells two popular models of digital SLR cameras. The sales of these products are not independent; if the price of one increases, the sales of the other increases. In economics, these two camera models are called substitutable products. 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 (N) and price (P) of each model.
(a) Construct a model for the total revenue and implement it on a spreadsheet. What is the profit (in dollars) predicted by your model when the price of model A is PA = $260 and the price of model B is PB = $320.

NA = 165 -0.7PA + 0.45PB
NB = 322 +0.08PA - 0.6PB
(b) Develop a two-way data table to estimate the optimal prices for each product in order to maximize the total revenue. Vary each price from $250 to $500 in increments of $10.

- Please calculate the total cost of providing a 50% subsidy on purchases of fruit and vegetables at farmers markets by SNAP participants. Assume that you are estimating it for the state of Connecticut with 350,000 SNAP participants. The season for farmers markets and the use of subsidies is 5 months (May-September); subsidies can only be used during this period. Based on prior studies, you know that a typical SNAP participant that attends farmers markets will purchase on average 3 lb of fruit and 2 lb of vegetables per month. Average price for vegetables is $1.5 per lb and the price elasticity of demand for vegetables among SNAP participants is -0.6. Similarly, fruit cost on average $2.5 per lb and the demand elasticity for fruit is -0.8. How much should the state of Connecticut expect to pay in total subsidies each season if only 20% of SNAP participants will attend farmers markets?arrow_forwardch 13. 3:arrow_forwardKroger, the country's leading grocery-only chain, added a line of private latbel organic and natural foods call Simple Truth to its stores. If you've priced organic foods, you know they are more expensive. For example, a dozen conventionally farmed Grade-A eggs at Kroger costs consumers $1.5, whereas Simple Truth eggs are priced at $3.5 per dozen. One study found that, overall, the average price of organic foods is 85 percent more than that of conventional foods. However, if prices get too high, consumers will not purchase the organic options. One element of sustainability is organic farming, which costs much more than conventional farming, and those higher costs are passed on to consumers. Suppose that a conventional egg farmer's average fixed costs per year for conventionally-farmed eggs are $1 milion per year, but an organic egg farmer's fixed costs are four times that amount. Further assume that the organic farmer's variable costs of $2.7 per dozen are three times as much as…arrow_forward
- You have just been employed as the quantitative analyst by a budget event organizing firm.Your task is to maximize the firm's total revenue.The admission fee to their weekend program for business students,"Board Room Discussion" is $10 and the average attendance is 1000 students.Analysis from the recent survey conducted by the marketing department show that every $1 reduction in the admission fee will attract 200 more students to attend.The records also show that every student who attends the event spends $5 on one of their publications. Required: i. State the total revenue function of the firm. ii. Estimate the admission fee that maximizes total revenue and total revenue at that price.arrow_forwardShow calculationsarrow_forwardLast month you assumed the position of manager for a large car dealership. The distinguishing feature of this dealership is its “no hassle” pricing strategy; prices (usually well below the sticker price) are posted on the windows, and your sales staff has a reputation for not negotiating with customers. Last year, your company spent $2 million on advertisements to inform customers about its “no hassle” policy and had overall sales revenue of $40 million. A recent study from an agency on Madison Avenue indicates that, for each 3 percent increase in TV advertising expenditures, a car dealer can expect to sell 12 percent more cars—but that it would take a 4 percent decrease in price to generate the same 12 percent increase in units sold. Assuming the information from Madison Avenue is correct, should you increase or decrease your firm’s level of advertising? Explainarrow_forward
- Pls help ASAP on this question (57)arrow_forwardSue is a customer account representative for ABC Company. She recently acquired several new accounts when a previous representative, Dan, took an early retirement. Sue reviewed each of Dan’s accounts to help familiarize herself with his clients and understand how she can better serve each one’s individual needs. As she was reviewing the client list, she found a major customer she had never heard of before. Surprised that she had not yet done business with the company, she called it to introduce herself as the new representative. When Sue placed the call, she found that the reported number had been disconnected. Thinking that the customer may have done business with ABC in the past and have moved on, she reviewed the account transactions and found that the most recent transaction had taken place the week prior. During her review, she also noticed the latest transaction was for an unusually large amount for ABC. As Sue pursued her curiosity, she went to other employees to find out more…arrow_forwardABC is an online-to-offline platform that sells e-commerce products to offline customersthrough a network of agents.

- Aliyah is preparing to expand her IT consulting company. The current market rate for IT professionals is $58,000 per year. Each employee she hires will also require a computer and equipment that costs $6,000 per employee annually. Hiring more employees means that Aliyah can provide consulting services to more clients each year. Each client Aliyah has will pay her $15,000 per year. The number of clients Aliyah can take on depends on the number of workers she hires as shown in the accompanying table. What is the marginal cost and marginal benefit of hiring each worker? Using the Rational Rule to maximize her economic surplus, how many workers should Aliyah hire? Number of workers Clients per year 0 0 1 11 2 20 3 27 4 32arrow_forwardOne of the oldest principles of marketing is that sellers may sell features, but buyers essentially buy benefits. This is a distinction sometimes lost on technology ledorganizations, and the service sector is no exception. Recent experience of the UK’s largest telecommunications company, Della’s, illustrates how crucial it is to see service offers in terms of the benefits they bring to customers. The company was aware of extensive research which had found high levels of confusion among purchasers of mobile phones, with a seemingly infinite permutation of features and prices. With four main networks to choose from, dozens of tariffs and hundreds of handsets, it is easy to see why buyers sought a way of simplifying their buying process. Throughout the 1990s, Della’s had positioned its UK network as superior technically to its competitors. Advertising focused on high coverage rates and call reliability.Della’s was the UK's most popular mobile phone operator, with almost eight million…arrow_forwardKing of HeartsThe King of Hearts, a neighborhood pub in a small midwestern town, is owned and operated by Mags Doherty. Since it opened in 2001, annual sales have increased from $200,000 to $500,000. She carries a wide selection of domestic and imported beers. She reports that 55% of her sales are derived from beer, 30 percent from mixed drinks, and the remainder from menu items such as sandwiches, French fries, and potato chips. Many customers have asked Mags to add pizza to her menu. She would have to spend $8,000 for an oven and $4000 for dishes. The ingredients in a typical pizza would cost $10.00 and the additional labor expense per pizza would be $0.80. The utilities involved in preparing each pizza would be $0.20. She would sell a pizza for $21.00.QuestionsWhat is her breakeven point in units and dollars? Show your calculations. Assume she sells 100 pizzas a day. How long will it take her to break even?
