Let S = senior citizen and c = child:
Day 1: 3S + 1C = $38
Day 2: 3S + 2C = $52
Difference between day 1 and 2 in money = 52 - 38 = 14
The only difference in ticket amounts was 1 child ticket, so 1 child ticket cost $14.
Using Day 1, subtract 14 from the total and then divide by 3 to find the price of a senior ticket:
38 - 14 = 24
24 / 3 = 8
A senior citizen ticket cost $8
