3 u |
5 u |
|
Total value |
21 u |
10 u |
31 u |
Price of 1 child ticket = 3 u
Price of 7 child tickets = 7 x 3 u = 21 u
Price of 1 adult ticket = 5 u
Price of 2 adult tickets = 2 x 5 u = 10 u
Total cost of the tickets
= 21 u + 10 u
= 31 u
31 u = 155
1 u = 155 ÷ 31 = 5
Price of a child ticket
= 3 u
= 3 x 5
= $15
Answer(s): $15
