| Value |
3 u |
7 u |
|
| Total value |
9 u |
28 u |
37 u |
Price of 1 child ticket = 3 u
Price of 3 child tickets = 3 x 3 u = 9 u
Price of 1 adult ticket = 7 u
Price of 4 adult tickets = 4 x 7 u = 28 u
Total cost of the tickets
= 9 u + 28 u
= 37 u
37 u = 111
1 u = 111 ÷ 37 = 3
Price of an adult ticket
= 7 u
= 7 x 3
= $21
Answer(s): $21
