Answer:
189 tickets sold on Saturday.
Explanation:
Your ratio of 8:1 is children's tickets to adult tickets.
There are 8 times as many children tickets sold as adult tickets.
Let c = # children's tickets
Let a = # adult tickets
8a = a + 147
subtract a from both sides
7a = 147
divide on both sides by 7
a = 147/7
find number of adult tickets
a = 21 adult tickets
multiply the number of adult tickets by 8 to find children's tickets 21*8=168
168+21=189 tickets sold on Saturday.
