Total |
| Number |
4 |
9 |
|
| Value |
2 u |
3 u |
|
| Total value |
8 u |
27 u |
35 u |
Price of 1 child ticket = 2 u
Price of 4 child tickets = 4 x 2 u = 8 u
Price of 1 adult ticket = 3 u
Price of 9 adult tickets = 9 x 3 u = 27 u
Total cost of the tickets
= 8 u + 27 u
= 35 u
35 u = 140
1 u = 140 ÷ 35 = 4
Price of a child ticket
= 2 u
= 2 x 4
= $8
Answer(s): $8
