Answer 1

50 children tickets; 60 adult tickets

Explanation:

Let a = number of adult tickets.

Let c = number of children tickets.

a + c = 110

5a + 3c = 450

-3a - 3c = -330

5a + 3c = 450

------------------------

2a = 120

a = 60

a + c = 110

c = 50

Answer: 50 children tickets; 60 adult tickets
