<span> correlation is the answer</span>
You can substitute 20 + d for c in the first equation which gives you
20+ d = 100 - d then solve
2d = 80
d= 40
then put the value for d back into one of the original equations
c= 20 + d
c = 20 + (40)
c = 60
<span>Current
employee = 40 340
A year ago a company has 40 340 – 24% employee.
Simply subtract 24% of 40 340 from 40 340 to get the number of employees last
year
=> 24% = .24
=> 40 340 x 0.24
=> 9681.6
Now, let’s subtract this 24% from the total number of employees in the current
=> 40 340 – 9 681.6 or 9682
=> 30 658.4 or 30 658
The number of employee last year before it increased 24%</span>
