•Bonnie is 36 weeks and her physician is concerned that the fetus is showing signs of distress.  She orders a “lung profile” which consists of determining the L/S ratio and measuring the percent phosphatidylglycerol (PG) on amniotic fluid.  The results are:

•L/S ratio = 1.0

•PG ratio = 0.3%

1.What is the interpretation of these test results?

Nilam Patel is the primary stockholder in two hotel corporations. One corporation owns a 90‐room economy property located in the suburbs of a large western town. The other corporation is a 350‐room full‐service convention hotel in the downtown city center for which Nilam has employed a management company to operate the property. Nilam is preparing balance sheets for both properties using a common size format. Complete the two balance sheets. Then answer the questions that follow.

1. What was the amount of cash in the 90‐room property's Cash in House Banks account at year end?
2. What is the amount of Allowance for Doubtful Accounts in the 350‐room property? Do you think it is excessive? Explain your answer?
3. What would explain the lack of a beverage inventory value in the 90‐room hotel?
4. What was the dollar amount of Total Assets in the 90‐room hotel?
5. What was the dollar amount of Total Assets in the 350‐room hotel?
6. What was the dollar amount of Current Maturities of Long‐Term Debt in the 350‐room property? Why is that amount likely so much higher than for the 90‐room property?
7. What was the dollar amount of Paid in Capital for the 90‐room property?
8. What is the Owners' Equity percentage of Total Assets in the 90‐room property? What is it in the 350‐room property?

The following equation represents the weekly demand that a local theater faces.

Qd = 2000 - 25 P + 2 A,

where P represents price and A is the number of weekly advertisements.

Presently the theater advertises 125 times per week. Assuming this is the only theater in town, and its marginal cost, MC, is equal to zero,

a. Determine the profit-maximizing ticket price for the theater.

b. What is the price elasticity of its demand at this price?

c. What is the elasticity of its demand with respect to advertising?

d. Now suppose the theater increases the number of its ads to 250. Should the theater increase its price following this ad campaign? Explain.

Consider a salient-role generator delivering power through a short transmission line to an infinite bus V∞=1∠0°, |Ea|=1.5. The active power delivered to the infinite bus is 0.7. We are given the generator reactances Xd=1.6 and Xq=1.0 and the line reactance XL=0.3. Neglect resistances, draw the phasor diagram and find Ea and Ia.
