The projected number of men and women enrolled in US colleges, in millions, is modeled in the following formulas: Women: N=0.007x+4.1 Men: N=0.01x +3.9
N represents enrollment, in millions, x years after 1984 (I left this part out last posting).
What is the project enrollment of women in 2004, and what is the projected enrollment of men in 2004?
With x equaling years after 1984, should I subtract 1984 from 2004 to get 20 years then multiply this by 0.007 for the women? What is the +4.1? Do I multiply 4.1 times 20 years also? I’m not sure how to put this into an equation. My guess:
See previous post.
