Total |
| Number |
7 |
2 |
|
| Value |
2 u |
3 u |
|
| Total value |
14 u |
6 u |
20 u |
Price of 1 child ticket = 2 u
Price of 7 child tickets = 7 x 2 u = 14 u
Price of 1 adult ticket = 3 u
Price of 2 adult tickets = 2 x 3 u = 6 u
Total cost of the tickets
= 14 u + 6 u
= 20 u
20 u = 40
1 u = 40 ÷ 20 = 2
Price of a child ticket
= 2 u
= 2 x 2
= $4
Answer(s): $4
