| Value |
2 u |
7 u |
|
| Total value |
4 u |
28 u |
32 u |
Price of 1 child ticket = 2 u
Price of 2 child tickets = 2 x 2 u = 4 u
Price of 1 adult ticket = 7 u
Price of 4 adult tickets = 4 x 7 u = 28 u
Total cost of the tickets
= 4 u + 28 u
= 32 u
32 u = 128
1 u = 128 ÷ 32 = 4
Price of a child ticket
= 2 u
= 2 x 4
= $8
Answer(s): $8
