11a.) 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. show your work
