China's GDP vs. United States' GDP I. It is widely predicted that China's economy, mea- sured by Gross Domestic Product (GDP), will even- tually overtake that of the United States. Table 3.17 shows the GDPs for China and the United States from 2005 and projected to 2040 under the assump- tion that China's GDP will grow at an average annual rate of 6.5% and that the United States' GDP will grow at an average annual rate of 2%. Investigate when China's GDP will reach that of the United States under these assumptions about the countries" growth rates by using the following steps. 1. a.
