Question 204138: The number of women, W, in millions, enrolled in colleges x years after 1984 can be approximated by W = 0.01x + 3.9. (Blitzer, 2007). When x = 16, W = 0.01(16) + 3.9 = 4.06. This implies that in the year 2000 (16 years from 1984) there were approximately 4.06 million women enrolled in colleges. When x = 20, W = 0.01(20) + 3.9 = 4.1. This implies that in the year 2004 (20 years from 1984) there were approximately 4.1 million women enrolled in colleges.
