(a).
Write a function that models the total number of men and women employed in the United States during this time.
(a).

Answer to Problem 51PPS
Explanation of Solution
Given:
The number of women and men age 16 and over employed each year in the United States can be modeled by the following equations, where x is the number of years since 1994 and y is the number of people in thousands.
women :
men:
Calculation:
For the total number of men and women employed in the United States during this time , that is , since 1994 ,
We have to add the number of women and men (in thousands) , so the function will be:
where x is the number of years since 1994 and y is the number of people in thousands.
(b).
If f is the function for the number of men, and g is the function for the number of women , what does
(b).

Answer to Problem 51PPS
Explanation of Solution
Given:
The number of women and men age 16 and over employed each year in the United States can be modeled by the following equations, where x is the number of years since 1994 and y is the number of people in thousands.
women :
men:
Calculation:
Or, in other words , it is the difference in the employment of men and women.
