3     0.24    0.18   0.6    0.3    0.2 

 

 [ 3  /  [0.24 - .18 ]  * [0.6 / 0.3] * 0.2 ]  

 

[  [3 / .06 ]   * [0.6 / 0.3] * 0.2 ]

 

[  50  *   2   *  .2  ]  =

 

[ 100 * .2 ]  =   20

3 / (0.24 - 0.18) x 0.6 / 0.3 x 0.2 =

3 / 0.06  x  0.6 / 0.3 x 0.2=

50  x  0.6 / 0.3  x 0.2=

30 / 0.3  x 0.2 =

100 x 0.2 =20
