Question 1183142: (Women in labor force) The number of women in the labor force is expected to increase in 1990s, but not as
dramatically as occurred during the 1970s. One forecasting consultant uses the linear equation n = 29.6 + 1.20 t
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 t equals 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 1995. In the year 2000.
The chamber of commerce for a summer resort is trying to determine how many tourists will be visiting each
season over the coming years. A marketing research firm has estimated that the number of tourists can be
predicted by the equation p = 275,000 + 7,500 t, where p = number of tourists per year and t = years (measured
from this current season). Thus t = 0 identifies the current season, t = 1 is the next season, etc. If p is plotted on
the vertical axis:
(a) Graph the equation.
(b) Identify the slope and y-intercept (p-intercept here).
(c) Interpret the meaning of the slope and p-intercept in this application.

You can put this solution on YOUR website! .
One and ONLY ONE problem/question per post.
It is the RULE, the POLICY and the REQUIREMENT of this forum.
It is written in this page
https://www.algebra.com/tutors/students/ask.mpl?action=ask_question&topic=Equations&return_url=http://www.algebra.com/algebra/homework/equations/
from which you post your problems.
It is assumed that you read these rules before posting.
It is also assumed that you do understand what is written in that page and follow the rules.
Those who violate them, work against their own interests.
