Basta calcular regra de tres:

8.000 ------------ 100%
  x       ------------  125%
100x = 125*8000
100x = 1000000
x = 1000000/100
x = 10.000  e o valor de 125% talque somando temos 18.000 

50.000  -------------- 100%
  x           -------------- 0,4%
100x = 50000*0,4
100x = 20000
x = 20000/100
x = 200

40000 -------------- 100%
x          --------------  1,2%
100x = 40000*1,2
100x = 48000
x = 48000/100
x = 480.

400 -------------- 100%
  x    --------------  3%
100x = 400*3
100x = 1200
x = 1200/100
x = 12.

8.600 ------------- 100%
x         -------------  18%
100x = 8600*18
100x = 154800
x = 154800/100
x = 1548.
