Total |
| Number |
8 |
3 |
|
| Value |
1 u |
2 u |
|
| Total value |
8 u |
6 u |
14 u |
Price of 1 child ticket = 1 u
Price of 8 child tickets = 8 x 1 u = 8 u
Price of 1 adult ticket = 2 u
Price of 3 adult tickets = 3 x 2 u = 6 u
Total cost of the tickets
= 8 u + 6 u
= 14 u
14 u = 70
1 u = 70 ÷ 14 = 5
Price of an adult ticket
= 2 u
= 2 x 5
= $10
Answer(s): $10
