From the early 1980's through 2012, the number of adults enrolled in Bachelor Degree programs has steadily increased. In 1983, 10.8 million adults were in enrolled in a Bachelor Degree program while in 2012, 20.6 million adults were enrolled. Write an approximate linear equation that would model these data where t = time in years after 1983 and B is the number of adults in millions in the US in a Bachelor Degree program. (Source: http:/ces.ed.gov/) (a) B = 0.338t + 20.6 (b) B = -0.338t + 20.6 (c) B = 0.338t - 10.8 (d) B = 0.338t + 10.8 11b.) Use this model to predict the 2016 Bachelor Degree students enrollment.
