By using U.S. Bureau of Labor Statistics data from 1950 and projected to 2050, the number of women in the workforce (in millions) can be described by W = 0.79x + 20.86, where x equals the number of years past 1950.
(a) Use a graphing calculator to graph this equation with x-min = 0 to x-max = 100 and with W-min = 0 to W-max = 100.
(b) The point (86, 88.8) lies on the graph of this equation. Explain its meaning.
(c) Find the projected number of women in the workforce in 2040 according to this model?
