A large electric utility company spews 66 million tons of greenhouse gases​ (mostly carbon​ dioxide) into the environment each year. This company has committed to spending $2.3 billion in capital over the next five years to reduce its annual emissions by 5​%. More will be spent after five years to reduce greenhouse gases further. a. What is the implicit cost of a ton of greenhouse​ gas? b. If the United States produces 4 billion tons of greenhouse gases each​ year, how much capital must be spent to reduce total emissions by 3​% over the next five years based on your answer in Part​ (a)?

F2 * Please use the accompanying Excel data set or accompanying Text file data set when completing the following exercise. An article in the Journal of Agricultural Science ["The Use of Residual Maximum Likelihood to Model Grain Quality Characteristics of Wheat with Variety, Climatic and Nitrogen Fertilizer Effects" (1997, Vol. 128, pp. 135-142)] investigated means of wheat grain crude protein content (CP) and Hagberg falling number (HFN) surveyed in the UK. The analysis used a variety of nitrogen fertilizer applications (kg N/ha), temperature (°C), and total monthly rainfall (mm). The data shown below describe temperatures for wheat grown at Harper Adams Agricultural College between 1982 and 1993. The temperatures measured in June were obtained as follows: 14.9 15.3 13.6 14.6 12.1 14.3 14.2 13.8 14.2 11.3 12.2 Assume that the population has a normal distribution and the standard deviation is known to be σ = 0.3.

Let's estimate how much Germany paid for imported natural gas in 2017. How much gas did Germany import on net in 2017? Subtract exports from imports, and answer in billions of cubic meters. (Answer should be in bcm) wwwww What was Germany's average import price? Answer in dollars per million BTU. Answer should be in $/MMBTU How much did Germany pay for its gas imports in 2017? Answer should be in $ . Hint (1 of 2): Hint for Germany and natural gas: look for a table in the natural gas section entitled "Gas Trade in 2016 and 2017" . Hint (2 of 2): You will need the energy density of natural gas - how much energy it has per cubic meter. For Record use BP's Statistical Review of World Energy, 2018

Suppose your company has just discovered $90,000 worth​ (this is the original manufacturing​ cost) of obsolete inventory in an old warehouse. Your boss asks you to evaluate two​ options: (1) remachine the obsolete parts at a cost of $29,000 and then hopefully resell them for $62,000 or​ (2) scrap them for $14,500 cash​ (which is​ certain) through a secondhand market. What recommendation would you make to your​ boss?
