The wavelengths of absorption of chromophores in electronic spectra are often influenced by the solvent. For example, polar solvents stabilize the ground state of n --> π transitions (n is a non-bonding orbital that is carried over into the molecular orbital scheme) more than the excited state. On the other hand, for π to π* transitions, the excited state is more stabilized. Sketch diagrams to show the changes in energy levels involved in the electronic transition when a chromophore changes from a nonpolar to a polar solvent environment and predict the shift in wavelength in each case.

3. Which of the following is NOT one of the three primary ways that a manufacturer could use extra profits earned from implementing a new cost-saving machine?

A consumer allocates all of her income between two goods, food and clothing, with the quantity of food consumed captured by the variable F while that of clothing by the variable C. The consumer has usual strictly convex preferences between the two goods. Assume that food is an inferior good and it is kept on the horizontal axis.

Suppose that the consumer’s income remains unchanged but prices of both of these goods change.

The price changes you need to examine is assume that both prices fall with price of food falling by a higher percentage relative to clothing.

(a)

State the impact of the price changes you are required to examine on the relative price of food.

(b)

Determine whether clothing should be treated as a normal or inferior good and explain your answer.

(c)

Now proceed with doing a geometric analysis to portray one case that is logically consistent with the price change scenario you need to examine as specified in (a). In doing so, illustrate and explain how the consumer’s optimal bundle might change in response to the cumulative impact of these price changes.

(d)

Comment on whether the direction of total change in optimal quantities of food and clothing that you have shown in your diagram for part (c) are the only logically consistent possibilities. Or, is it also possible that changes could also be in the opposite direction? Explain your answer. You do not need to do additional diagrammatic analysis to answer this part.

a.has a price elasticity of demand less than negative one

b.has an income elasticity of demand less than one

c.has an income elasticity of demand less than zero

d.is the same as a necessity

a.the rate at which consumers substitute for one good as its price changes

b.the rate at which utility changes as consumption bundles change

c.the rate at which total substitution changes as overall consumption changes

d.the rate at which consumers substitute one good for another while staying on the same indifference curve

Describe the ways in which quality and cost are controlled in your chosen facilities. Also discuss the ethical aspect of access to care in the facilities, including rationing.
Based on your observations and learning from the two facilities, discuss the changes brought in the long-term care system to make it reach full status as a competition-driven system. You may include the following points in your discussion:

·      Discuss the changes made in the control mechanisms (external and internal) in order to control the management, financing, and quality in the long-term care systems.

·      Discuss the changes taking place in long-term care reimbursement system in order to provide better reimbursement options both to consumers and providers.

·      Discuss the changes made in the efforts of providers to accommodate changing magnitude of the day-to-day needs of long-term care consumers.

Kaelea, Inc., has no debt outstanding and a total market value of $90,000. Earnings before interest and taxes, EBIT, are projected to be $8,000 if economic conditions are normal. If there is strong expansion in the economy, then EBIT will be 20 percent higher. If there is a recession, then EBIT will be 30 percent lower. The company is considering a $34,000 debt issue with an interest rate of 6 percent. The proceeds will be used to repurchase shares of stock. There are currently 3,600 shares outstanding. Assume the company has a market-to-book ratio of 1.0.

b. Calculate the percentage changes in ROE when the economy expands or enters a recession, assuming no taxes.

Assume the firm goes through with the proposed recapitalization and no taxes.
c. Calculate return on equity, ROE, under each of the three economic scenarios after the recapitalization.

d. Calculate the percentage changes in ROE for economic expansion and recession.

Assume the firm has a tax rate of 35 percent.
e. Calculate return on equity, ROE, under each of the three economic scenarios before any debt is issued. Also, calculate the percentage changes in ROE for economic expansion and recession.

f. Calculate return on equity, ROE, under each of the three economic scenarios after the recapitalization. Also, calculate the percentage changes in ROE for economic expansion and recession, assuming the firm goes through with the proposed recapitalization.

5.3 BEP Example

Bill Braddock is considering opening a Fast ‘n Clean Car Service Center. He estimates that the following costs will be incurred during his first year of operations: Rent $9,200, Depreciation on equipment $7,000, Wages $16,400, Motor oil $2.00 per quart. He estimates that each oil change will require 5 quarts of oil. Oil filters will cost $3.00 each. He must also pay The Fast ‘n Clean Corporation a franchise fee of $1.10 per oil change, since he will operate the business as a franchise. In addition, utility costs are expected to behave in relation to the number of oil changes as follows:

                     Number of Oil Changes                Utility Costs

                                 4,000                                   $ 6,000

                                 6,000                                   $ 7,300

                                 9,000                                   $ 9,600

                               12,000                                   $12,600

                               14,000                                   $15,000

Bill Braddock anticipates that he can provide the oil change service with a filter at $25 each.

Problem 19-4A Mary Willis is the advertising manager for Bargain Shoe Store. She is currently working on a major promotional campaign. Her ideas include the installation of a new lighting system and increased display space that will add $57,600 in fixed costs to the $396,000 currently spent. In addition, Mary is proposing that a 5% price decrease ($60 to $57) will produce a 20% increase in sales volume (20,000 to 24,000). Variable costs will remain at $36 per pair of shoes. Management is impressed with Mary’s ideas but concerned about the effects that these changes will have on the break-even point and the margin of safety. Compute the current break-even point in units, and compare it to the break-even point in units if Mary’s ideas are used. (Round answers to 0 decimal places, e.g. 1,225.)
