Adult ticket |
Total |
| Number |
6 |
9 |
|
| Value |
2 u |
3 u |
|
| Total value |
12 u |
27 u |
39 u |
Price of 1 child ticket = 2 u
Price of 6 child tickets = 6 x 2 u = 12 u
Price of 1 adult ticket = 3 u
Price of 9 adult tickets = 9 x 3 u = 27 u
Total cost of the tickets
= 12 u + 27 u
= 39 u
39 u = 78
1 u = 78 ÷ 39 = 2
Price of a child ticket
= 2 u
= 2 x 2
= $4
Answer(s): $4
