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

Adult ticket |
Total |
| Number |
7 |
9 |
|
| Value |
2 u |
5 u |
|
| Total value |
14 u |
45 u |
59 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 9 adult tickets = 9 x 5 u = 45 u
Total cost of the tickets
= 14 u + 45 u
= 59 u
59 u = 118
1 u = 118 ÷ 59 = 2
Price of a child ticket
= 2 u
= 2 x 2
= $4
Answer(s): $4
