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

| Value |
3 u |
5 u |
|
| Total value |
15 u |
25 u |
40 u |
Price of 1 child ticket = 3 u
Price of 5 child tickets = 5 x 3 u = 15 u
Price of 1 adult ticket = 5 u
Price of 5 adult tickets = 5 x 5 u = 25 u
Total cost of the tickets
= 15 u + 25 u
= 40 u
40 u = 160
1 u = 160 ÷ 40 = 4
Price of a child ticket
= 3 u
= 3 x 4
= $12
Answer(s): $12
