as with all word problems, translate the words to symbols. Then you have equations which can be solved.

If there are a adult and c child tickets, you have two sets of facts: the number of tickets and their cost.

c + a = 64
1.00c + 2.50a = 109.00

Now you can use your math skills to solve those equations.
number of adult tickets --- x
number of student tickets -- y

x + y = 64
2.5x + y = 109

subtract the two equations to get x = ...

then sub back into the first equation to get y
