Polaski Company manufactures and sells a single product called a Ret. Operating at capacity, the company can produce and sell 40,000 Rets per year. Costs associated with this level of production and sales are given below:

The Rets normally sell for $46 each. Fixed manufacturing overhead is $200,000 per year within the range of 35,000 through 40,000 Rets per year.

Required:

1. Assume that due to a recession, Polaski Company expects to sell only 35,000 Rets through regular channels next year. A large retail chain has offered to purchase 5,000 Rets if Polaski is willing to accept a 16% discount off the regular price. There would be no sales commissions on this order; thus, variable selling expenses would be slashed by 75%. However, Polaski Company would have to purchase a special machine to engrave the retail chain’s name on the 5,000 units. This machine would cost $10,000. Polaski Company has no assurance that the retail chain will purchase additional units in the future. What is the financial advantage (disadvantage) of accepting the special order? (Round your intermediate calculations to 2 decimal places.)

2. Refer to the original data. Assume again that Polaski Company expects to sell only 35,000 Rets through regular channels next year. The U.S. Army would like to make a one-time-only purchase of 5,000 Rets. The Army would pay a fixed fee of $1.80 per Ret, and it would reimburse Polaski Company for all costs of production (variable and fixed) associated with the units. Because the army would pick up the Rets with its own trucks, there would be no variable selling expenses associated with this order. What is the financial advantage (disadvantage) of accepting the U.S. Army's special order?

3. Assume the same situation as described in (2) above, except that the company expects to sell 40,000 Rets through regular channels next year. Thus, accepting the U.S. Army’s order would require giving up regular sales of 5,000 Rets. Given this new information, what is the financial advantage (disadvantage) of accepting the U.S. Army's special order?

A steel reaction vessel at 25 oC initially contained pure NO2 at a concentration of 2.0 x 10-4 mol/L. Some of the NO2 reacted to form N2O4 as described by the following equilibrum equation:

2NO2(g) <----------> N2O4(g)

At equilibrium, the concentration of N2O4 was found to be 6.01 x 10-6 mol/L. What is the concentration-based equilibrium constant (Kc) for this reaction at 25 oC?

I know the correct answer is 170, but I'd like to know how to get there. Thanks!

2. What is the pH of 3 mM H3PO4 solution? If you wish to adjust the pH of 1 L of that solution to 7.4, how much H+ or OH— do you need (in mmol)? At pH 7.4 what is the concentration of H2PO4 —? The pKas of H3PO4 are 2.1, 7.1 and 12.3.

Multi-part questions: Packer Fan Tours is the official tour company for the Green Bay Packers of the NFL. One of the events in the package is to sponsor a reception the night before a game for fans that is attended by 5 of the players from the team. There are 53 players on the Green Bay Packers' roster of which 22 are starters. Assume that the 6 players attending the reception this week are chosen randomly. Determine the probability of the following occurring:

a. None of the players at the reception are starters.

b. All of the players at the reception are starters.

c. Two of the players at the reception are starters.

d. Four of the players at the reception are starters.

Extensive research into the efficacy of maintaining high Vitamin D3 levels has proven that Vitamin D3 is more efficacious at preventing the Flu virus than vaccination.

1a) Briefly describe what happens during the three steps of DNA synthesis in E. coli. Remember to list what enzymes/proteins are needed and what their function is. How is the lagging strand different? What direction does synthesis proceed in? 15 points.

2b) The t_RNA with the incoming amino acid binds at the _____ site, and translocation occurs with the peptidyl t_RNA moving to the ____ site.

When one company (A) buys another company(B), some workers of company B are terminated. Terminated workers get severance pay. To be fair, company A fixes the severance payment to company B workers as equivalent to company A workers who were terminated in the last one year. A 36-year-old Mohammed, worked for company B for the last 10 years earning 32000 per year, was terminated with a severance pay of 5 weeks of salary. Bill smith complained that this is unfair that someone with the same credentials worked in company A received more. You are called in to settle the dispute. You are told that severance is determined by three factors; age, length of service with the company and the pay. You have randomly taken a sample of 40 employees of company A terminated last year. You recorded

Number of weeks of severance pay

Age of employee

Number of years with the company

Annual pay in 1000s

2. How much variance is not explained by the model? Test the validity of the models that X predict Y (provide hypotheses, decision, conclusion and conclusion in the business context)

An object is thrown straight up into the air. The object leaves the person’s hand with an upward velocity of magnitude 27 m/s. Assume that the object is in free fall, i.e., neglect air resistance. Draw a motion diagram and graphs (two graphs: one for vertical position vs. time, and one for vertical velocity vs. time) from the time when the object leaves the person’s hand to 5.0 seconds later. Include all the information on the graph that you can determine about the object’s motion, such as its position and velocity at 5.0 seconds. Assume that the person does not catch the object or interfere with it during the 5.0 seconds time interval.

If so, what is the angle between the stick's force and the puck's displacement? c) Is it possible that the stick does -6.0 J of work on the puck? If so, what is the angle between the stick's force and the puck's displacement? d) Is it possible that the stick does 6.0 J of work on the puck? If so, what is the angle between the stick's force and the puck's displacement? e) If the puck possesses an initial speed of 4.0 m/s, and then 4.0 J of work is done on the puck, find its final speed. Ignore friction. f) If the puck possesses an initial speed of 4.0 m/s, and then -2.0 J of work is done on the puck, find its final speed. Ignore friction.

Place the following energy states in order of their least net carbon dixide emission into the atmosphere, where 1. = lowest net carbon, and 5. = highest net carbon.

In your calculation, take into account:

1. How much carbon dioxide (or CO2 equivalent) is emitted per unit energy generated.
2. If the source is renewable, how much carbon dixide (or CO2 equivalent) is removed from the atmosphere each year by that resource.
3. How much energy is needed to produce and deliver that energy source.

Oils. Petroleum fractions, plant oils, and similar viscous substances, ccommonly combined with lighter distillates to form diesel fuels for truck and rail engines.   

Gaseous. Hydrocarbons, hydrogen and carbon monoxide mixtures present in gaseous state at room temperatures which, when combined with oxygen (burned) release heat and/or light.   

Solid fuels. Fossil carbonates (coals and peat), carbonized woody materials (coke, charcoals, and biochars), and lignite (woody) fuels including wood, pelletized grasses, etc. burned directly in their solid state.  

Distillates. Highly flammable liquids (liquid at room temperature) distilled from petroleum (gasoline), fermented plant starches (ethanol) and plant oils ("green" kerosene), used in both turbine (jet) and internal combustion engines.
