In 2006, U.S. output was $13.2 trillion, and Chinese output was $2.8 trillion. Suppose that from now on, the output of China grows at an annual rate of 8.8% per year (roughly what it has done during the past decade), while the output of the United States grows at an annual rate of 3.4% per year.
Using these assumptions and a spreadsheet, plot U.S. and Chinese output over the next 100 years. How many years will it take for China to have a level of output equal to that of United States?
