| Number |
3 |
5 |
|
| Value |
5 u |
6 u |
|
| Total value |
15 u |
30 u |
45 u |
Price of 1 child ticket = 5 u
Price of 3 child tickets = 3 x 5 u = 15 u
Price of 1 adult ticket = 6 u
Price of 5 adult tickets = 5 x 6 u = 30 u
Total cost of the tickets
= 15 u + 30 u
= 45 u
45 u = 90
1 u = 90 ÷ 45 = 2
Price of a child ticket
= 5 u
= 5 x 2
= $10
Answer(s): $10
