EXERCISE

Listed below are 10 industries. Classify each one as (a) emerging, (b) rapid-growth, (c) mature/slow-growth, (d) stagnant/declining, or (e) high-velocity/turbulent, and (f) fragmented. Do research on the Internet, if needed, to locate information on industry conditions and reach a conclusion on what classification to assign each of the following:

• (1) Exercise and fitness industry
• (2) Dry cleaning industry
• (3) Poultry industry
• (4) Camera film and film-developing industry
• (5) Wine, beer, and liquor retailing
• (6) Watch industry
• (7) Cell phone industry
• (8) Recorded music industry (CDs, tapes)

The firm has calculated the deman functions for each market as follows:

NY market p = 150-Q

LA market p = 50-Q

Total cost function estimate = TC = 40Q.

Calculate the following:

a. quantity, total revenue and profit when the company maximizes its profit and changes the same price in both markets.

b. quantity, total revenue and profit when the company charges different prices in each market and maximizes its total profit.

Company has signed a contract that requires tanhem to produce and sell 60,000 units for $8 per units. A regression model was run using 27 observations to measure total costs as a function of units. It is as follows:

Total costs = $100,000 + $6 per unit

The standard error of the estimate is $8,000.

Required:

a. Calculate the following assuming certainty:

i). Breakeven in units and in dollars

ii) Sales quantity in needed to obtain an after-tax profit of $24,000. Assume that a 40 percent tax rate is used for only part 2.

iii) Sales in dollars needed to obtain a pretax profit equal to 10 percent of sales.

b. Calculate the following assuming uncertainty:

i) What is the range of incomes that would be expected with 90 percent confidence?

ii)What is the probability that the firm will make a profit next year?

Suppose demand for inkjet printers is estimated to be QD = 1000 - 5p + 10pX - 2pZ + 0.1Y. If p = 80, pX = 50, pZ = 150, and Y = 20,000; answer the following:

1. What is the price elasticity of demand? 
2. What is the cross-price elasticity concerning commodity X? Give an example of what commodity X might be. 
3. What is the cross-price elasticity concerning commodity Z? Give an example of what commodity Z might be. 
4. What is the income elasticity? 

A company produces and sells a consumer product and can control the demand for the product by varying the selling price. The approximate relationship between price and demand is

P=$38 + (2,700/D ) - (4,900/D^2), for D>1

where p is the price per unit in dollars and D is the demand per month. The company is seeking to maximize its profit. The fixed cost is $1,100 per month and the variable cost (Cv) is $ 41 per unit.

a. What is the number of units that should be produced and sold each month to maximize profit? ( round the nearest whole number)

b. Show that your answer to Part (a) maximizes profit.

The demand for Good X is given by Qx = 4000-Px-2Py+4Pz +0.2M where Py is the price of good Y, Pz is the price of good Z, and M is income, if Py =$800, Pz = $200 and M= $5000 determine the following:

1. The inverse demand function for good X.

2. Whether good Y is a substitute or complement for good X. explain why.

3. Whether doog Z is a substitute or completement for good X. explain why

4. Whether good X is a normal or inferior good. explain why

Suppose Lester's utility is only a function of a good (commodity X) and a bad (commodity Y). Does Lester consider X to be a normal or an inferior good or is it not possible to tell? Explain your answer carefully.

A company produces x units of commodity A and y units of commodity B each hour. The company can sell all of its units when commodity A sells for P=90-5x dollars per unit and commodity B sells for P=70+4y dollars per unit. The cost (in dollars) of producing these units is given by the joint-cost function C(x,y)=5xy+3. How much of commodity A and commodity B should be sold in order to maximize profit?

Commodity A:______

Commodity B:______

How does commodity money different from fiat money?

Summarize the influence supply and demand have on our economy. Use the following points as prompts as you formulate your answer.

a. Law of supply.

b. Law of demand.

c. Supply and demand affecting equilibrium price.

d. Factors that affect supply.

e. Factors that affect demand.

Please differentiate A = W * L wrt to t

d/dt (A) = d/dt (w * l)

A norman window has the shape of a rectangle surmounted byasemicircle. (Thus the diameter of the semicircle is equal tothewidth of the rectangle.) If the perimeter of the window is 30ft,find the dimensions of the window so that the greatestpossibleamount of light is admitted.

Differentiate.

Question

In the fruit fly Drosophila, a rudimentary wing called “vestigial” and dark body color called “ebony” are inherited at independently assorting genes and are recessive to their dominant wild-type counterparts, full wings and gray body color. Wild-type males and females heterozygous for both traits are crossed, and 3200 progeny are produced.

How many progeny flies are expected to be found in each phenotypic class?
