Question 1207001
<br>
The ratio of adult tickets to senior tickets was 9:2. Given that information,<br>
Let 9x = # of adult tickets
Let 2x = # of senior tickets<br>
The ratio of adult tickets to child tickets was 3:2.  Since the number of adult tickets is 9x, the number of child tickets is 6x.<br>
The total number of tickets was 187:<br>
9x+2x+6x = 187
17x = 187
x = 187/17 = 11<br>
# of adult tickets: 9x = 99
# of senior tickets: 2x = 22
# of child tickets: 6x = 66<br>
