Kilgore's Deli is a small delicatessen located near a major university. Kilgore's does a large walk-in carry-out lunch business. The deli offers two luncheon chili specials, Wimpy and Dial 911. At the beginning of the day, Kilgore needs to decide how much of each special to make (he always sells out of whatever he makes). The profit on one serving of Wimpy is $0.45, on one serving of Dial 911, $0.58. Each serving of Wimpy requires 0.25 pound of beef, 0.25 cup of onions, and 5 ounces of Kilgore's special sauce. Each serving of Dial 911 requires 0.25 pound of beef, 0.4 cup of onions, 2 ounces of Kilgore's special sauce, and 5 ounces of hot sauce. Today, Kilgore has 20 pounds of beef, 15 cups of onions, 88 ounces of Kilgore's special sauce, and 60 ounces of hot sauce on hand.

A bacterial strain called XYZ living in the lake MBG223 near Bilkent University requires to synthesize tryptophan continuously. The reason is, the essential proteins (essential means, the proteins required for survival of the bacteria) contain high content of tryptophan. Therefore, this bacterial strain XYZ has a tryptophan operon. Unfortunately, the tryptophan level of nutrition available in lake MBG223 is very limited during summer and winter time and the other nutrition levels are high. During the summer time, as the lake MBG223 partially evaporates, the salinity of the water increases, the temperature of the lake arises and the pH of the environment turns from natural to acidic. Changes in salinity, pH and temperature is known to disrupt hydrogen bonding in nucleotide base-pairings and also the structure of the proteins. Here, assuming that the structure/function of the proteins are not effected please answer the followings.
a) İnside the XYZ bacteria, what would you observe with regards to synthesis of tryptophan bearing proteins during summer vs. winter time? How would this effect bacterial growth rate during the summer time vs winter time? (18pts)
b) In another neighboring lake called MBG222, they found a different bacterial strain called WOWWW to have mutant tRNAs on the anti-codon region of the tRNA. This tRNA carries Phenylalanine to wherever it encounters the sequence UGG (tryptophan) on the mRNA. What happens to the regulation of the trypthophan operon in bacteria that has 1) high tryptophan and low phenylalanine vs. bacteria that has low tryptophan and high phenylalanine? (12 pts)

Natalie owns a condominium near Cocoa Beach in Florida. This
year, she incurs the following expenses in connection with her
condo:
| Insurance | $ | 1,350 |
| Advertising expense | 735 | |
| Mortgage interest | 5,050 | |
| Property taxes | 1,110 | |
| Repairs & maintenance | 1,120 | |
| Utilities | 1,440 | |
| Depreciation | 12,200 | |
During the year, Natalie rented out the condo for 85 days,
receiving $22,750 of gross income. She personally used the condo
for 39 days during her vacation.
Assume Natalie uses the Tax Court method of allocating expenses to rental use of the property. Assume 366 days in the current year. (Do not round intermediate calculations. Round your final answers to the nearest whole dollar amount.)
a. What is the total amount of for AGI (rental) deductions Natalie may deduct in the current year related to the condo?
b. What is the total amount of itemized deductions Natalie may deduct in the current year related to the condo?
c. If Natalie’s basis in the condo at the beginning of the year was $178,000, what is her basis in the condo at the end of the year?
d. Assume that gross rental revenue was $4,550 (rather than $22,750). What amount of for AGI deductions may Natalie deduct in the current year related to the condo?

3. McHuffter Condominiums, Inc., of Pensacola, Florida, recently purchased land near the Gulf of Mexico and is attempting to determine the size of the condominium development it should build. Three sizes of develop-ment are being considered; Small, d1; Medium, d2; and large, d3. At the same time, an uncertain economy makes it difficult to ascertain the demand for the new condominiums. McHuffter's management realizes that a large development followed by a low demand could be very costly to the company. However, if McHuffter makes a conservative small-development decision and then finds a high demand, the firm's profits will be lower than they might have been. With the three levels of demand-low, medium and high. McHuffter's management has prepared the following profit ($000). (20 pts.)

Small, d1 400 400 400
Medium, d2 100 600 600
Large, d3 -300 300 900
--------------------------------------------
a) If nothing is known about the demand probabilities, what are the recommended decision using the Maximax(optimistic), Maximin (pessi- mistic), and Minimax regret approaches?
b) If P(low) = 0.20, P(medium) = 0.35, and P(high) = 0.45, What is the recommended decision using the expected value approach?
c) What is the expected value of perfect information (EVPI)? You have to use regret table to get EVPI.
Suppose that before making a final decision, McHuffter is considering
conducting a survey to help evaluate the demand for the new condominium
development. The survey report is anticipated to indicate one of two
levels of demand: weak(W) or strong(S). The relevant probabilities are as
follows: (25 pts)
P(W)= 0.3 P(low/W) = 0.50 P(low/S) = 0.10
P(S)= 0.7 P(medium/W)= 0.40 P(medium/S)= 0.25
P(high/W) = 0.10 P(high/S) = 0.65

d) Construct a decision tree for this problem and analyze it.
e) What is McHuffter’s optimal decision?
f) What is the expected value of the survey(sample) information?

An analyst has created estimates for a new Putt Putt course near the local elementary school. The course will require an investment (building and equipment) at year 0 of $166,994.00. This amount can be depreciated over 5 years using the straight-line approach. The building can be sold for an NSV of $42,903.00 in year 5. The entrepreneur needs help estimating the cash flows for the business.
