Jester's Deli sells 640 sandwiches at a price of $8 each. A market survey shows that for every $0.10 reduction in price, 40 more sandwiches will be sold. Let x represent the number of $0.10 reductions.
Describe a cost function for a business venture. What are the two kinds of costs that are modeled by this function?
Suppose you are the marketing manager of a firm, and you plan to introduce a new product to the market. You have to estimate the first year net profit, which depends on several variables • Sales volume (in units) • Price per unit • Unit cost . Fixed costs Your net profit is net profit = sales volume x (price per unit-unit cost) - fixed cost The fixed cost is $120, 000, but other factors have some uncertainty. Based on your market research, there are equal chance that the market will be slow, ok, or hot. • Slow market the sales volume follows Poisson distribution with mean 50,000 units product, and the average price per unit is $11.00 ● Ok market the sales volume follows Poisson distribution with mean 75,000 units product, the average price per unit is $10.00 Hot market: the sales volume follows Poisson distribution with mean 100,000 units product, but the competition is severe so you expect the average price per unit is just $8.00 No matter what the market type is, your average unit…
Step 1 The average cost function is given as A(q) = 125/q+ q2/16 -4, where q is the firm's output. 1. What part of the decreasing range is practically feasible? 2. Write an equation for the total cost function. 3. Hence calculate the level of output for which total costs are minimum.
Two competing companies produce mobile phones. Company A starts production at 1000 phones per week and plans to increase output by 200 each week. Company B starts production with 500 phones per week and plans to increase output by 20% each week. (a) Calculate the weekly production in weeks 1; 5; 10; 15. Plot the graph of weekly output for each producer on the same diagram (use Excel, if available). Estimate the week in which the output is the same for both firms. (b) Calculate the total production during the first 15 weeks for each firm.
6. The start up are running business and want to minimize equipment expenses. For a particular piece of equipment, the costs can be broken into initial outlays to buy the equipment, fixed annual expenses to keep the equipment in the inventory, and repair costs which we anticipate rising as the equipment gets older. A widget press costs 10,000B to buy, and the operating expenses are 500 per year, and the total repair costs are 300t² over the first t years. What is the optimal length of time to use a widget press before replacing it? You should shown your answer algebraically and graphically.
Yaster Breakfast Supplies is planning to manufacture and market a new toaster. After conducting extensive market surveys, the research department provides the following estimates: • a weekly demand of 318 at a price of $13 per toaster • a weekly demand of 201 at a price of $16 per toaster The financial department estimates that weekly fixed costs will be $1,399 and variable costs (cost per unit) will be $3. Assume: • the relationship between price and demand is linear • the cost function in linear Use your models to predict the marginal profit when Yaster is producing and selling 271 toasters per week. Round to the nearest cent. $ per toaster
