1. According to the U.S. Census Bureau, the population of the United States in 2008 was 304 million people. In addition, the population of the United States was growing at a rate of 1.1% per year. Assuming this growth rate continues, the model P(t)= 304 (1.011)^t-2008

represents the population P (in millions of people) in year t

According to the model, when will the population be 443 million people? Be sure to round your answer to the nearest whole year.
