Women in the Labor Force The number of women in the labor force is expected to increase during the 1990s, but not as dramatically as occurred during the 1970s. One
forecasting consultant uses the linear equation n = 29.6.+ 1.20t to predict the number of women between the ages of 35 and 44 who will be in the labor force. In this equation, n equals the number of women (aged 35 to 44) in the labor force (measured in millions) and
tequals time measured in years since 1981 (t = 0 corresponds to 1981). If n is plotted on the vertical axis:
(a) Graph the equation.
(b) Identify the slope and y intercept (n intercept, here).
(c) Interpret the meaning of the slope and n intercept in this application.
(d) Predict the number of women in this age group who will be in the labor force in 1955.
In the year 2000.

(b) Identify the slope and y-intercept (n-intercept here)
(c) Interpret the meaning of the slope and n-intercept in this application.
(d) Predict the number of women in this age group who will be in the labor force in 1995. In the year 2000.
