25 of the price of an adult ticket, what was the price of an adult ticket?

Total |
| Number |
7 |
5 |
|
| Value |
2 u |
5 u |
|
| Total value |
14 u |
25 u |
39 u |
Price of 1 child ticket = 2 u
Price of 7 child tickets = 7 x 2 u = 14 u
Price of 1 adult ticket = 5 u
Price of 5 adult tickets = 5 x 5 u = 25 u
Total cost of the tickets
= 14 u + 25 u
= 39 u
39 u = 195
1 u = 195 ÷ 39 = 5
Price of a child ticket
= 2 u
= 2 x 5
= $10
Answer(s): $10
