c) The approximate number of years it takes for the real GDP per capita in Japan to double if the real GDP growth rate and the population growth rate is maintained (use the "Rule of 70" for this arithmetic of growth)

QUESTION 7 Suppose that Japan's real GDP was 525 trillion yen in 2009 and 535 trillion yen in 2010. Meanwhile, Japan's population was 127.6 million in 2009 and 127.5 million in 2010. Calculate: a) The real GDP growth rate. b The growth rate of real GDP per capita. Clarify the standard of living from value in (a). The approximate number of years it takes for the real GDP per capita in Japan to double if the real GDP growth rate and the population growth rate is maintained (use the "Rule "
