Answer:
189 tickets
Explanation:
Given,
The ratio of child and adult tickets = 8: 1
Let, the number of child tickets = 8x and adult tickets = 1x
Where, x is any positive real number number,
Since, there are 147 more child tickets then adult tickets,
⇒ Child tickets = Adult tickets + 147
⇒ 8x = x + 147
⇒ 8x - x = 147
⇒ 7x = 147
⇒ x = 21
Hence, the total number of tickets sold = 8x + x = 9x = 9(21) = 189
