Answer:

189

Explanation:

Child : Adult  = 8 : 1

So, let the no of child tickets = 8x

No. of  adult tickets = x

On Saturday,

8x - x = 147

       7x = 147

         x = 147/7

         x = 21

No of child tickets =  x  + 147 = 21 + 147 = 168

Total no. of tickets sold on Saturday = 168 + 21 = 189
