.

 a +  c =  600,   (1)    (counting tickets)
8a + 5c = 4116.   (2)    (counting dollars)


To solve, express c = 600-a from (1) and substitute it into (2). You will get the single equation for a:

8a + 5*(600-a) = 4116.

Simplify and solve it.  Then evaluate  c = 600-a.

It is very standard problem on tickets (actually, on solving systems of linear equations in 2 unknowns).
