 Y = k/X    Inverse Variation Statement
 
 3 = k / 25            //  Y = 3 WHEN X = 25 . Substitute values.
 
 k = 75          //  Constant of Proportionality
                                             
 Y = 75 / X          //  Y as a Function of  
                                             
 Y = (75 / 7 )       //  X = 7 . Substitute value.
 
 Y = (75 / 7 )       //  Y WHEN X = 7
