let the number of adult tickets be x and the number of children tickets be y
x:y = 8:1
On Saturday, x = 147 + y
(147+y):y = 8:1
[tex] \frac{147}{y} + [tex] \frac{y}{y} = 8 + 1
[tex] \frac{147}{y} = 8
147 = 8y
∴y = 88
x = 147 + 88
∴ x = 235
so the no of tickets sold on saturday = 235 + 88 = 323

Answer:
Step-by-step explanation:
This book has 500 pages in total.
We should split up the place values.
1 - 9
One only appears once.
1
10 - 19
One appears 11 times.
1 + 11
20 - 99
One only appears 8 times.
1 + 11 + 8
Add:
1 + 11 + 8
=> 20
Since the same is for 200-299, and so on. Let us add twenty four times.
20 * 4
=> 80
Looking back to 100-199, there are 120 ones.
Add:
120 + 80
=> 200
