The per capita GDP is calculated by dividing a country's GDP by its population. Ethiopia's per capita GDP is $145.45, while Costa Rica's is $2,250, making Costa Rica's per capita GDP significantly higher.
The student is asking for the average wage of an accountant in Ethiopia, but provided information about the GDP of Ethiopia and Costa Rica for a different calculation. Since the question's content does not match what the student is asking, I will answer the calculation question provided.
To calculate the per capita GDP of each country, you must divide the total GDP of the country by its population. For Ethiopia, with a GDP of $8 billion and a population of 55 million, the per capita GDP is:
Per capita GDP = GDP / Population
Per capita GDP of Ethiopia = $8 billion / 55 million
Per capita GDP of Ethiopia = $145.45
For Costa Rica, with a GDP of $9 billion and a population of 4 million, the per capita GDP is:
Per capita GDP of Costa Rica = $9 billion / 4 million
Per capita GDP of Costa Rica = $2,250
Comparing the two, Costa Rica's per capita GDP is much higher than Ethiopia's.
