Answer:
Option A is the cheapest.
Explanation:
Giving the following information:
The engineering department estimates costs of $450,000 for the first year. It is estimated that if process and plant alterations are made, the waste treatment cost will decline $43,000 each year. As an alternative, a specialized firm, Hydro-Clean, has offered a contract to process the waste liquids for 15 years for $225,000 per year.
We need to use the following formula and chose the smallest net present value:
NPV= Io +∑ [Cf/(1+i)^n]
Option A:
Io= 407,000
Year cost= 43,000
NPV= 734,061
Option B:
Yearly cost= 225,000
NPV= 1,936,368
Explanation:
1. The ceterus paribus effect gives us to what extent, the effect of a variable has on another variable, while holding all other factors fixed. Analysing job training of workers on productivity will give us results that are not biased since we will not be taking account of other factor variables in the calculations. When 2 firms are the same in almost every aspect apart from number of hours on training, then we will find out that each firm would have different levels of workers output. So we should know if workers output increases due to job training.
2. When it comes to provision of training, furms do these based on characteristics of the workers. Some of these characteristics are measurable while some are immeasurable
Measurable:
Experience on the job,
Productivity
Level of education,
immeasurable :
Skill set
Vision
Likeliness to bstay at firm
3. Apart from worker characteristics, productivity also depends on other factors one of which is technological change. A technological change can bring about increased efficiency and greater output by the worker. Different firms using different capital and technological combination are quite likely to have different output levels.
4. A positive correlation between job training and productivity cannot be used to ascertain if job training makes worker more efficient this is due to the fact that correlation only tells us if variables are in coexistence. So a positive correlation does not tell us that job training is indeed bringing about changes in the productivity of workers.
Answer:
the economic order quantity is 845 units
Explanation:
The computation of the economic order quantity is shown below;
As we know that
Economic order quantity is
= √2 × √annual demand × √ordering cost ÷ √carrying cost
= (√2 × √6750 × √$225) ÷ (√4.25)
= √3,037,500 ÷ √4.25
= √7,14,705.88
= 845 units
Hence, the economic order quantity is 845 units
Price discrimination is the action of selling the same product at different prices to different buyers, in order to maximize sales and profits. Movie theaters practice it by giving discounts on certain night. Example: senior citizens discount. Restaurants practice price discrimination by menu pricing.
Tax multiplier = -1.5
Tax increase = $200 billion
Therefore, since the multiplier is a negative value, the GDP must have gone down.
GDP = Tax increase/Tax multiplier = 200/-1.5 = $133.33 billion decrease.
Then, the correct answer is c.
