The answer is A 102
120*0.85= 102
Let the variable x represent the answer. 

85% [tex]= 0.85 = 85 / 100 [/tex]

[tex]120/x=100/85[/tex]

[tex](120/x)*x=(100/85)*x [/tex]  

      - 
we multiply both sides of the equation by x

[tex]120=1.17647058824*x [/tex] 

     - 
we divide both sides of the equation by (1.17647058824) to get x

[tex]120/1.17647058824=x [/tex]

[tex] x=102[/tex]
