Answer:
$129 000/yr
Step-by-step explanation:
Weighted average is used to answer this question.
<em>total employees are 20</em>
10 employees make 80 000
<em>total earning for 10 employees </em>= 80 000 * 10 = 800 000 (multiplying)
6 employees make 150 000
<em>total earning for 6 employees= </em>150 000 * 6 =900 000<em> (multiplying)</em>
4 employees make 220 000
<em>total earning for 4 employees </em>= 220 000 * 4 = 880 00<em>0 (multiplying)</em>
<em />
<em>To calculate weighted average all the totals are added and then divide by total number of employees.</em>
<em>weighted average =</em> (800 000 + 900 000 + 880 000)/20
<em />
<em>weighted average = </em>2580000/20
<em />
<em>Weighted average = </em>129 000

Given:
The equation of a line is:
A line passes through the point (-5,-3) and perpendicular to the given line.
To find:
The equation of the line.
Solution:
Slope intercept form of a line is:
...(i)
Where, m is the slope and b is the y-intercept.
We have,
...(ii)
On comparing (i) and (ii), we get
We know that the product of slopes of two perpendicular lines is always -1.
Slope of the required line is 
and it passes through the point (-5,-3). So, the equation of the line is:
Using distributive property, we get
Therefore, the equation of the line is . Hence, option A is correct.
