| Value |
3 u |
5 u |
|
| Total value |
12 u |
45 u |
57 u |
Price of 1 child ticket = 3 u
Price of 4 child tickets = 4 x 3 u = 12 u
Price of 1 adult ticket = 5 u
Price of 9 adult tickets = 9 x 5 u = 45 u
Total cost of the tickets
= 12 u + 45 u
= 57 u
57 u = 171
1 u = 171 ÷ 57 = 3
Price of a child ticket
= 3 u
= 3 x 3
= $9
Answer(s): $9
