Let the number of child tickets sold be x
Number of child tickets = x
Number of adult tickets = x + 50
Total cost of child tickets = 5x
Total cost of adult tickets = 10(x + 50)
5x + 10 (x+ 50) = 2060
5x + 10x + 500 = 2060
15x + 500 = 2060
15x = 2060 - 500
15x = 1560
x = 104
Number of child tickets sold = 104
Number of adult tickets sold = 104 + 50 = 154
