A company is considering the purchase of an industrial laser for $150,000. The device has a useful life of five years and a salvage (market) value of $30,000 at the end of those five years. Annual revenues are estimated to be $55,000 per year. Annual expenses are guaranteed to be $10,000 per year. Using a MARR = 18%, determine how sensitive the decision is to changes in the estimate of annual revenues? Express your answer as a percent change from the estimated value of $55,000. Write a sentence explaining the meaning of your answer.

In 2017, X Company had the following selling price and per-unit variable cost information:

In 2017, total fixed costs were $643,000.

In 2018, there are only two expected changes. Direct material costs are expected to decrease by $8 per unit, and fixed selling and administrative costs are expected to increase by $10,000. What must unit sales be in order for X Company to break even in 2018?

1. What are the three inventory accounts? List them, describe them and provide an example of the types of costs included in each inventory account.

2. What is the relevant range? Why would cost behaviour changes outside the relevant range? In your answer, describe an example (or examples) in your response.

3. Compare and contrast committed fixed costs and discretionary fixed costs. in your answer, provide at least one example of each type of cost and explain why it is a committed fixed cost or a discretionary fixed cost.

HR Industries (HRI) has a beta of 1.5, while LR Industries's (LRI) beta is 0.7. The risk-free rate is 6%, and the required rate of return on an average stock is 13%. The expected rate of inflation built into r_RF falls by 1.5 percentage points; the real risk-free rate remains constant; the required return on the market falls to 10.5%; and all betas remain constant. After all of these changes, what will be the difference in the required returns for HRI and LRI? Round your answer to two decimal places.

: A suspension of colloids at room temperature (25°C) contains CaS0₄ in (a) 3 mM and (b) 30 mM concentration. Find the Debye length (in nm) for both the cases. Use relevant data given in lecture 12-13. (c) Why do you suppose the Debye length changes with change in salt concentration? Provide reasoning from colloidal science to support your answer. (d) If NaCI was used instead of CaS0₄, how would the Debye length values change for cases (a) and (b)? (No calculation necessary for part (d))

Mr. and Mrs. B have four children. All were seemingly healthy pregnancies, without complications. When the last child was tested for PKU shortly after birth (as required by law), the results indicated toxic levels of phenylalanine breakdown products in the blood.

Explain how dietary changes can affect the expression of PKU. (See Autosomal Recessive Disorders—Phenylketonuria.)

Discuss the cause of the disease and the probable percentages of inheritance of the disease in children the couple might have in the future. (See Autosomal Recessive Disorders—PKU.)

For each of the following statements, please indicate if it is TRUE or FALSE. Then provide a justification or explanation of your answer to each question in less than 30 words.

1. The golden-rule state for an economy with constant population but where the effective supply of labour grows at a steady rate refers to a condition such that consumption of the total population is maximised.
2. The equation, Y = MV/P, implies that, if the velocity (V) does not change when the money supply (M) changes, then the government can raise national income (Y) by printing more money (M).

21. A mother’s use of cigarettes and alcohol is most damaging to the fetus during the third trimester of pregnancy.

22. It is possible for healthy individuals to be carriers for a dominant genetic disease.

23. “Phenotype” refers to the allelic composition of an individual while “genotype” is what is expressed.  

24. Transcription refers to the process of transferring DNA sequence information to RNA.

25. There is little scientific consensus regarding the idea that current global climate change is largely human-induced.

26. The term “anthropogenic” refers to changes in the environment that are naturally-occurring.  

Until recently, the US Dollar had been appreciating. This was occurring as the growth rates of European and some Asian economies were slowing. Based on these two trends only, how would the rate of growth for the US economy change from its previous levels (provide your basis for this). What should the effect of these two factors be on interest rates, the S&P 500 index, and commodity prices (briefly provide your basis for each of these changes).
