Given:
The ratio of child and adult tickets = 8:1
sold 147 more child tickets than adult tickets
To Find:
Number of tickets sold on Saturday in the amusement park = ?
Solution:
Let
The number of child ticket be x
The number of adult ticket be y
Then from the ratio we know that there are 8 child ticket than adult ticket
=> x =8y------------------------------(1)
Also, they sold 147 more child tickets than adult tickets
=> x = 147 +y--------------------------(2)
Equating (1) and (2)
8y = 147 +y
8y-y = 147
7y=147
y =
y =21
So The number of adult tickets were 21
Now the child ticket
x = 147 +y
x = 147+21
x= 168
Total tickets = adult ticket + child ticket
=>21 +168
