The table to the right gives the per capita gross nationalproduct and the per capita expenditure on defense for eightdeveloped countries. Gross domestic product? (GDP) is a measure ofthe total economic output of a country in monetary terms. Percapita GDP is the GDP averaged over every person in the country.Complete parts a though c.
