Over the past century, real GDP per person in the United States has grown about percent per year, which means it doubles about every years. a. 2, 14 b. 2, 35 c. 5, 14

The correct answer is letter "B": 2; 35.

Explanation:

A company's Gross Domestic Product (GDP) represents its productivity over a certain period but the GDP per person or GDP per capita represents a country's productivity related to its number of inhabitants. Researches from the year 1870 until 2014 show that in the U.S. the GDP per capita at the beginning was around $4,300 and by 2014 it was almost $56,000.

The GDP per capita growth rate is 2% (1,8% exactly) which by the Pareto rule of 70/30, it implies:

Then, every 35 years the GDP per capita in the U.S. has grown 2% over the past decade (until 2014).
