| Value |
1 u |
2 u |
|
| Total value |
2 u |
6 u |
8 u |
Price of 1 child ticket = 1 u
Price of 2 child tickets = 2 x 1 u = 2 u
Price of 1 adult ticket = 2 u
Price of 3 adult tickets = 3 x 2 u = 6 u
Total cost of the tickets
= 2 u + 6 u
= 8 u
8 u = 144
1 u = 144 ÷ 8 = 18
Price of an adult ticket
= 2 u
= 2 x 18
= $36
Answer(s): $36
