Review the chart to answer the question that follows. Total PopulationGDP Country A5,00010,000 Country B10,00015,000 Country C2,0008,000 Country D1,0005,000 Using only this chart, which step would you take first to compare the standard of living in these countries? Add the GDP numbers for the countries to get a total. Divide each GDP number by its country's population. Subtract each population number from its country's GDP. Multiply the population number by the GDP for each country.

Divide each GDP number by its country's population

Explanation:

Country - - - - - Total Population - - - - GDP

Country A - - - - - - 5,000 - - - - - - - 10,000

Country B - - - - - - 10,000 - - - - - - 15,000

Country C - - - - - - - 2,000 - - - - - - 8,000

Country D - - - - - - - 1,000 - - - - - - - 5,000

Using only the data above, to determine the standard of living, we need to calculate the GDP per capita which is used to evaluate a country living standard by evaluating a country's economic output per person.

It is obtained by getting the proportion of GDP and population.

COUNTRY A : 10000 / 5000 = 2

COUNTRY B: 15000 / 10000 = 1.5

COUNTRY C: 8000 / 2000 = 4

COUNTRY D: 5000 / 1000 = 5

USING the information above, COUNTRY D has the highest standard of living as they have the highest GDP(Gross Domestic Product) per capita.

the answer is d.index
