Answer:

B. 3% population growth and 5% real GDP growth

Explanation:

2012 GDP per person = 42,000,000 ÷ 10,000 = 4,200

Current population (at 3% growth rate) = 10,000 + (10,000 × 3%) = $10,300

Current real GDP (at 5% growth rate) = 42,000,000 + (42,000,000 × 5%) = 44,100,000.00

Current GDP per person = 44,100,000.00 ÷ 10,300 = $4,281.55

Growth rate of GDP per person = ($4,281.55 - 4,200)/4,200 = 0.0194, or 1.94%.
