Lucy bought 2 adult tickets and three children tickets and paid $33. Craig bought 5 adult tickets and one child ticket and paid $50. What would the amount of child tickets be and adult tickets be?

Answer 1

2A + 3C = 33

5A + C = 50

15A + 3C = 150

2A +3C = 33

13A = 117

A = 117/13 = $9 for an adult ticket

C = 50-45 = $5 for a child's ticket
