The infantwear buyer designed rompers for her department that she would bring in at a wholesale price of $96 per dozen and a coordinating T-Shirt at $72 per dozen. She brings in 30 dozen rompers and 40 dozen T-Shirts. She plans to mark the rompers at $16 each. At what does she have to mark the T-Shirts to acheive an avergae markup of 52%?
C.
A buyer is offered a group of windbreakers for boys that have
all the national basketball team logos. Some of the windbreakers
are hooded while some are not. The manufacturer will sell 165
windbreakers at a cost of $25 each and 200 hooded windbreakers at a

retail price. The departmental markup is 43%. What must the retail
price be for all the windbreakers to acheive that goal? To what do
you suggest the buyer round the price? Explain.

Advanced Analysis) Currently, at a price of $1 each,
100 popsicles are sold per day in the perpetually hot town of
Rostin. Consider the elasticity of supply. In the short run, a
price increase from $1 to $2 is unit elastic (Es = 1.0).
In the long run, a price increase from $1 to $2 has an elasticity
of supply of 1.50. (Hint: Apply the midpoints approach to the
elasticity of supply.)

1. Recall Ken Washington from the beginning of Chapter 35. Now that you have completed the chapter, answer the following questions regarding his case.
1. Is it significant that Ken had a urinary catheter in place for 6 days while he was in the hospital?
2. Dr. Buckwalter plans to send Ken home with a urinary catheter in place. What information can you give him to help him prevent infection?
3. You note on the chart that Dr. Buckwalter wants to see Ken again in 2 days. You ask Ken to schedule an appointment for that time. Ken’s wife states that they are going out of town for a week and will not be able to return until after that time. What should you tell Ken about making an appointment for more than a week?

Frankie's Homemade Cheese Shop ("Frankie's") signed an advertising agreement with Simmons Boards ("Owner") for billboard advertising rights along Route 33 in the town of Hampton. Frankie's has the right to select and display advertising copy on billboard panels numbered 10 and 12 (panel numbers correspond to designated billboard locations) for a 3-year period from Jan. 1, 20X1, to Dec. 31, 20X3. In consideration for these rights, Frankie's agrees to pay $10,000 in year 1, $12,000 in year 2, and $13,000 in year 3. Assume that Frankie's is required to pay the annual fee on Jan. 1 of each contract year. Assuming Frankie's incremental borrowing rate is 5%, what are the entries Frankie should record at inception of the contract, then at the end of years 1, 2, and 3?

The Chocolate Ice Cream Company and the Vanilla Ice Cream Company have agreed to merge and form Fudge Swirl Consolidated. Both companies are exactly alike except that they are located in different towns. The end-of-period value of each firm is determined by the weather, as shown below. There will be no synergy to the merger.
| State | Probability | Value | ||||
| Rainy | .3 | $ | 440,000 | |||
| Warm | .2 | 620,000 | ||||
| Hot | .5 | 1,160,000 | ||||
The weather conditions
in each town are independent of those in the other. Furthermore,
each company has an outstanding debt claim of $620,000. Assume that
no premiums are paid in the merger.
How much do
stockholders and bondholders each gain or lose if the merger is
undertaken? (A negative answer should be indicated by a
minus sign. Do not round intermediate
calculations.)

Suppose the economy has access to 1000 Mahogany trees, used for making guitars. Processing the trees for guitar production costs $1 per tree. This economy may access 1000 additional trees (perhaps existing in the outskirts of the town) but it costs $3 to use each of those trees. Assume 5 trees are needed to produce one guitar.
Questions : (1) What is the Supply curve for guitar production? You may answer with a fully labeled picture.
(2) If the demand function for guitars is D(p)=220-2p, what is the equilibrium price and quantity in the market for guitars?
(3) Suppose the government wants to incentivize people to play more guitar, so they place a subsidy of $5 per guitar. That is, if the consumer pays p, the firm gets p+5.

Part II: Evaluate Disaster Risk in Supply Chain
Suzy Jones is trying to decide whether to use one or two suppliers
for the motors than go into the chain saws that her company
produces. She wants to use local suppliers because her firm runs a
JIT operation. Her factory is located in a coastal town that is
prone to hurricanes. She estimates that the probability in any year
of a "super-event" that might shut down all suppliers at the same
time for at least two weeks is 5%. Such a total shutdown would cost
the company approximately $100,000. She estimates the
"unique-event" risk for any of the suppliers to be 10%. Assuming
that the marginal cost of managing an additional supplier is
$12,000 per year, should Suzy use one or two suppliers?
