Final answer:
The GDP per capita for Country A is calculated by dividing their GDP in millions ($1,500,000 million) by their population in millions (100 million), resulting in a GDP per capita of $15,000.
Step-by-step explanation:
To calculate the GDP per capita for Country A, we use the formula GDP per capita = GDP/population. According to the information provided, Country A has a GDP of $1.5 trillion and a population of 100 million. First, we convert the GDP from trillions to millions by multiplying by 1,000. This gives us $1,500,000 million. Then, we divide this number by the population, which is 100 million, to get the GDP per capita.
So, the calculation looks like this: ($1,500,000 million GDP) / (100 million people) = $15,000 per capita.
Therefore, the GDP per capita for Country A is $15,000, rounded to the nearest cent.
