1 u |
2 u |
|
Total value |
5 u |
16 u |
21 u |
Price of 1 child ticket = 1 u
Price of 5 child tickets = 5 x 1 u = 5 u
Price of 1 adult ticket = 2 u
Price of 8 adult tickets = 8 x 2 u = 16 u
Total cost of the tickets
= 5 u + 16 u
= 21 u
21 u = 42
1 u = 42 ÷ 21 = 2
Price of an adult ticket
= 2 u
= 2 x 2
= $4
Answer(s): $4
