Writing in 1829, former President James Madison made some predictions about the growth of the population of the United States. The populations he predicted fit the equation where y is the population in millions of people x years from 1829. Use the equation to determine the approximate year President Madison would have predicted that the U.S. population would reach 100,000,000. Round answer to the nearest year.
