| Value |
3 u |
5 u |
|
| Total value |
9 u |
20 u |
29 u |
Price of 1 child ticket = 3 u
Price of 3 child tickets = 3 x 3 u = 9 u
Price of 1 adult ticket = 5 u
Price of 4 adult tickets = 4 x 5 u = 20 u
Total cost of the tickets
= 9 u + 20 u
= 29 u
29 u = 145
1 u = 145 ÷ 29 = 5
Price of an adult ticket
= 5 u
= 5 x 5
= $25
Answer(s): $25
