Answer:
The statement that is correct is;
d. The 2015 sale reduced 2015 GDP by $20,000 and had no effect on 2007 GDP.
Step-by-step explanation:
GDP is known as the Gross Domestic Product. The GDP is a measure of the quantity of goods and services that are produced in a country during a certain period in time. The GDP is usually expressed in monetary terms. A high GDP usually translates to high levels of production. It is often used to determine how wealthy a country is in relation to the production capabilities. To determine a change in GDP, we need to determine the Net national product as follows;
NNP=GDP-D
where;
NNP=net national product
GDP=gross domestic product
D=depreciation
In our case;
NNP=$255,000
GDP=$275,000
D=d
replacing;
255,000=275,000-d
d=275,000-255,000=20,000
The depreciation=$20,000
The 2015 sale reduced 2015 GDP by $20,000 and had no effect on the 2007 GDP.
