3. The sales of film cameras in the United States decreased linearly from 14.73 million in 2001 to 7.33 million in 2005. (a) Find a linear function f giving the sales of film cameras (in millions) in year t, where t = 0 corresponds to 2000.
(b) In a complete sentence explain what the slope of the linear function that you found above means in the context of the problem. You should not use any mathematical terminology in your explanation.
(c) What were the sales of film cameras in 2004? State your answer in a complete sentence in the context of the problem.
4. The California emissions cap was set at 400 million metric tons of carbon dioxide equivalent in 2015 and is expected to drop linearly to 334 million metric tons in 2020.
(a) Find a linear function f giving the California emissions cap (in millions of metric tons) in year t, where t = 0 corresponds to 2000.
(b) In a complete sentence explain what the slope of the linear function that you found above means in the context of the problem. You should not use any mathematical terminology in your explanation.
