Total |
| Number |
5 |
4 |
|
| Value |
2 u |
3 u |
|
| Total value |
10 u |
12 u |
22 u |
Price of 1 child ticket = 2 u
Price of 5 child tickets = 5 x 2 u = 10 u
Price of 1 adult ticket = 3 u
Price of 4 adult tickets = 4 x 3 u = 12 u
Total cost of the tickets
= 10 u + 12 u
= 22 u
22 u = 132
1 u = 132 ÷ 22 = 6
Price of an adult ticket
= 3 u
= 3 x 6
= $18
Answer(s): $18
