| Number |

9 |
|
| Value |
2 u |
3 u |
|
| Total value |
6 u |
27 u |
33 u |
Price of 1 child ticket = 2 u
Price of 3 child tickets = 3 x 2 u = 6 u
Price of 1 adult ticket = 3 u
Price of 9 adult tickets = 9 x 3 u = 27 u
Total cost of the tickets
= 6 u + 27 u
= 33 u
33 u = 198
1 u = 198 ÷ 33 = 6
Price of a child ticket
= 2 u
= 2 x 6
= $12
Answer(s): $12
