In both Gamma and Delta average labor productivity is $20,000 per worker per year. The population of Gamma is 200,000 and the population of Delta is 400,000. Sixty percent of the population in each country is employed. Total output in Gamma is and total output in Delta is .

Total output in Gamma is $2,400,000,000 and total output in Delta is $4,800,000,000.

Explanation:

The population of Gamma is 200,000 and the population of Delta is 400,000. Sixty percent of the population in each country is employed.

The number of worker in Gamma = 60% x 200,000 = 120,000 people

The number of worker in Delta = 60% x 400,000 = 240,000 people

Total output = Average labor productivity x The number of worker

Total output in Gamma = $20,000 x 120,000 = $2,400,000,000

Total output in Delta = $20,000 x 240,000 = $4,800,000,000
