Let  "x"  be the number of children;  then the number of adults is  (2000-x).


The money equation is


    3x + 6*(2000-x) = 8100.


From the equation, express "x" and  calculate


    x =  = 1300.


ANSWER.  1300 children  and  200-1300 = 700 adults.


CHECK.   1300*3 + 700*6 = 8100 dollars.   ! Correct !

Solved.
