1.A nation's real GDP increased from $225 billion to $230 billion in one year. In that same year, the nation's population increased from 125 million to 126 million.
a. Calculate the nation's real GDP per capita growth rate.
b. If this nation maintained this growth rate, how many years would it take for real GDP per capita to double?

2.The graph below shows the aggregate production function of two nations, A and B. Suppose that in 1958 each nation had $100 of physical capital for each worker and in 2008 each nation had $400 of physical capital per worker.
Figure: Nations A and B
a. Compute the growth of real GDP per capita (between 1958 and 2008) for both nations.
b. Clearly in both 1958 and in 2008 nation A was producing more real output per capita with the same amount of physical capital per
