(a)

Answer to Problem 4LC
Explanation of Solution
Given:
According to the Bureau of Labor and Statistics, approximately 144,400,000 people were employed in the United States in 2013.
The number of people in production occupations times 17.5 is the number of working people.
Concept Used:
144,400,000 people were employed in the United States in 2013.
Number of working people is 17.5 times the number of people in production occupation.
Calculation:
Let the number of working people be X
Equation:
Solve:
Thus, the equation represent the situation is
(b)
Find the numbers of people are in repair occupation.
(b)

Answer to Problem 4LC
Explanation of Solution
Given:
According to the Bureau of Labor and Statistics, approximately 144,400,000 people were employed in the United States in 2013.
The number of people in repair occupations is 3,100,000 less than the number of people in production occupation.
Concept Used:
144,400,000 people were employed in the United States in 2013.
The number of people in repair occupations is 3,100,000 less than the number of people in production occupation.
Number of people in repair occupation is the difference between 144,400,000 and 3,100,000.
Calculation:
144,400,000 people were employed in the United States in 2013.
The number of people in repair occupations is 3,100,000 less than the number of people in production occupation.
Let the number of people in repair occupations is X.
The number of people in repair occupations is:
The number of people in repair occupations is
Thus, the number of people in repair occupations is
