i think a row of 5 squares would be sufficient.
this includes a header column and a header row.
it would look like this:
tickets sold       A          C         S         T
                   99         66        22        187


if you don't include the headers, then a row of 4 squares would be sufficient.

the calculations would be as follows:

you are given that:
A/C = 3/2
A/S = 9/2

from this you can derive the following:
C/A = 2/3
S/A = 2/9

if you solve for C, you get C = 2A/3
if you solve for S, you get S = 2A/9
by default, A = A/1.

you are given that A + C + S = 187
by substitution, this becomes A + 2A/3 + 2A/9 = 187
multiply both sides of this equation by 9 to get 9A + 6A + 2A = 1683
combine like terms to get 17A = 1683.
solve for A to get A = 99.

you get:
A = 99
C = 2A/3 = 66
S = 2A/9 = 22

that's your solution.

from your selections, your solution will be:

The number of adults tickets sold was 99.
The number of senior tickets sold was 22.
The number of child tickets sold was 66.

The ratio of adult tickets to senior tickets was 9:2. Given that information,

Let 9x = # of adult tickets
Let 2x = # of senior tickets

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.

The total number of tickets was 187:

9x+2x+6x = 187
17x = 187
x = 187/17 = 11

# of adult tickets: 9x = 99
# of senior tickets: 2x = 22
# of child tickets: 6x = 66
