Modeling Data With Linear functions, Trends and Forecasting

1. America creates more garbage than any other nation. According to Denis Hayes, president of Seattle's nonprofit Bullitt Foundations and a founder of Earth Day, "We need to be an Heirloom Society instead of a Throw-Away Society." The EPA estimates that, on average, we each produce 4.4 pounds of garbage daily (Source: Take out the Trash, and put it _where?" by Bernard Bavzer, Parade Magazine, June 13, 1999). The following graph illustrates the annual production of municipal solid waste in the U.S. for the years listed.

See attached file for full problem description.

a) Model the data with two linear functions. Let the independent variable represent the number of years after 1960.
b) With each function found in part a), predict the amount of municipal solid waste in 2005.
c) Which of the two models appears to fit the data more closely (the more realistic prediction)?
