.
Let a be the number of adults.  

Then the number of children is (5300-a).


You have this "money" equation (revenue)


    8.50a + 6.50*(5300 - a) = 38794.


From the equation,


    a =  = 2172.


ANSWER.  2172 adults.


CHECK.  8.50*2172 + 6.50*(5300-2172) = 38794 dollars.   ! Correct !

Solved.
