ycow [4]

Answer: The number of child tickets is 85 and the number of adult tickets is 95.

Step-by-step explanation:

Let C = Number of child tickets

A = Number of adult tickets.

As per given, we have

C+A=180          (i)

7C+13A=1830           (ii)

Multiply 7 to both sides of equation (ii), we get

7C+7A=1260     (iii)

Eliminate (iii) from (ii) , we get

6A=570\\\\\Rightarrow\ A=95

Put value of y in (i), we get

C= 85

Hence, the number of child tickets is 85 and the number of adult tickets is 95.
