| Value |
1 u |
3 u |
|
| Total value |
2 u |
18 u |
20 u |
Price of 1 child ticket = 1 u
Price of 2 child tickets = 2 x 1 u = 2 u
Price of 1 adult ticket = 3 u
Price of 6 adult tickets = 6 x 3 u = 18 u
Total cost of the tickets
= 2 u + 18 u
= 20 u
20 u = 80
1 u = 80 ÷ 20 = 4
Price of an adult ticket
= 3 u
= 3 x 4
= $12
Answer(s): $12
