2 |

| Value |
6 u |
7 u |
|
| Total value |
18 u |
14 u |
32 u |
Price of 1 child ticket = 6 u
Price of 3 child tickets = 3 x 6 u = 18 u
Price of 1 adult ticket = 7 u
Price of 2 adult tickets = 2 x 7 u = 14 u
Total cost of the tickets
= 18 u + 14 u
= 32 u
32 u = 128
1 u = 128 ÷ 32 = 4
Price of a child ticket
= 6 u
= 6 x 4
= $24
Answer(s): $24
