In the late 1970s, there was a major controversy over a dam built by the Tennessee Valley Authority called the Tellico Dam, which is located near the mouth of the Little Tennessee River. After construction was completed and almost all of the land purchases (or evictions) had been done, the Supreme Court ruled that it could not go on because of the presence in the Little Tennessee of a fish on the endangered species list called the Snail Darter. (Congress later voted to exempt the dam from the law and the dam was closed in the late fall of 1979, creating Tellico Lake.) While the economic benefits of the dam were admittedly dubious, one of the common arguments for completing the project was this: "We have spent more than $100 million to build this dam. We need to complete it because we will have wasted all this money otherwise." Please evaluate this argument from an economic point of view.

In a factory in which metal parts are degreased with organic solvents, the intern breaks a bottle containing a mixture of 5 liters of tetrachloroethylene (PER, MW = 166 g/mol, ρ = 1.62 g/cm3 , Pv = 18 mm Hg) and 10 liters of trichloroethene (TCE, MW = 131 g/mol, ρ = 1.46 g/cm3 , Pv = 54 mm Hg) in a closed room at 20oC. The room has a total volume of 50 m3 . Assume PER and TCE form an ideal mixture in the liquid phase.

a. What is the composition (in mole fractions) of the liquid mixture in the bottle?

b. What are the equilibrium concentrations of PER and TCE in the air of the room in mg/L? Note: Make sure to use Raoult’s Law. [PER] = 49.9 mg/L

c. What is the composition (in mole fractions) of the remaining liquid on the floor after equilibrium? XPER = 0.790

Madtack Company uses a job-order costing system and started the month of
March with three jobs in process. The cost of beginning work in process
plus the costs added during March are shown below:

                                  Job #359      Job #360      Job #361
beginning work in process .....    $4,800        $3,500        $5,300

COSTS ADDED DURING MARCH:
direct materials ..............    $4,100        $3,000        $6,400
direct labor ..................     5,000         3,900         4,000

Madtack applies overhead to jobs at a rate of 80% of direct materials
used. During March, Madtack completed and sold Job #361. Job #359 was
also completed but was not sold by the end of March. Job #360 was not
completed by the end of March. Madtack's actual overhead cost for the
month of March totaled $11,500.

Calculate Madtack's cost of goods sold for March after the overhead
variance is closed.

You are an audit senior at Sheerin& Associates and have noted the following independent issues in relation to the audit of Creek Ltd:

1. The Creek company Ltdusually carried out its stocktakeon balance date after it had closed its stores for the day but due to illness the stocktake was carried out twentydaysafter balance date.
2. The audit of the accounting system found numerous severe internal control weaknesses during the interim audit .
3. Due to increased competitive pressures, Creek Ltdhas recently moved the manufacture of some of its clothing lines out of Melbourne into regional areas. While Sleek Ltdsaves around 25% in costs, the manu­fac­tur­ing process takes longer and on several occasions late delivery has resulted in lost sales.

Required:

Explain the impact of each of these separate issues on your assessment of audit risk, the materiality level and the audit strategy that would be adopted.

ou are considering two different strategies for a savings account that you intend to close when you retire exactly 29 years from today. For Strategy 1, deposit $1,750 per quarter for 8 years (first deposit today; last one exactly 8 years from today); no new deposits will be made after the end of the deposit period, but interest continues to accrue until the account is closed. For Strategy 2, you’ll make your first quarterly deposit exactly 8 years from today, each quarterly deposit also equals $1,750 , and you’ll continue making quarterly deposits for 21 years, so that you make the final deposit exactly 29 years from today when you close the account. The savings rate always is 7.5% compounded quarterly. What will strategy 1 accumulate at retirement?

Lori, age 26, works as a waitress at an upscale restaurant in Dallas, Texas. After the restaurant closed one evening, she drove home in a blinding rainstorm. A drunk driver ran a red light, smashed head-on into Lori’s car, and was instantly killed. Lori was more fortunate. She lived but was unable to work for six months. During that time, she incurred medical bills in excess of $100,000 and lost about $20,000 in tips and wages. The restaurant did not provide any health or disability income insurance, whereas the driver had a life and health insurance plan.

Identify the major pure risks or pure loss exposures to which the drunk driver and Lori are exposed respectively with respect to each of the following. Explain your answer.

i) Personal loss exposures

ii) Property loss exposures

iii) Liability loss exposures

On June 1st 2016, Professor Cole bought an investment property for $400,000. He took out a standard 30 year fixed mortgage for $242000 at a nominal rate of 5.500% per year, with uniform monthly payments starting one month from the date of closing. He closed on June 1st, and paid on the first of each month after that. He paid all of the loans closing costs. What were his monthly mortgage payments? $  
When he filed his taxes for 2016, he needed to calculate the interest paid on the mortgage. He had made 6 payments, because the January 1st 2017 payment covered the interest charged in December 2016. How much interest did he pay in 2016? $  
Next year Professor Cole had to calculate his interest paid on the mortgage in 2017. How much interest was paid in 2017? $
