hi,
since we are looking to maximize the average with no change in earnings..
Let all the layed off employees were ding Social service :wink: that is they were working without any pay..

so if all 100%,say 100 earlier were earning 100 with average = 1..
Now 80% are earning 100 so average = 100/80 = 1.25..
increase = 1.25-1= .25
% = .25/1*100 = 25%
D

Let employees before layoff be 100 earning 1 Unit per employee.
After layoff number of employees =80 (Still earning 100 units)
Hence earning per employee = 100/80=5/4
5/4=1*(1/4)

1/4 is the increase and it corresponds to 25% increase.

Hence answer is D

We can assume that before the layoffs, Jackson Consulting (JC) has 10 employees and each is paid, on average, $100. Thus, the total payroll would be 10 x 100 = $1000. Since JC lays off 20% of its employees, it lays off 2 employees and we have 8 employees left. To maintain the total payroll of $1000, each of the 8 employees, on average, would be paid 1000/8 = $125.

We see that the average employee earnings of $125 after the layoffs is 25% more than the average employee earnings of $100 before the layoffs.

Answer: D
