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

Answer: The GDP deflator
Explanation: The GDP(gross domestic product) deflator is a price index that is used to measure the prices of all the goods and services produced within an economy. The cars which are exported by General Motors are produced domestically within the United States of America and exported outside the country.
Any goods produced externally are not considered when determining the GDP deflator.
