$1 |
|
| Total value |
3 u + 180 |
1 u |
4 u + 180 |
Cost of 1 child ticket = $1
Cost of 1 adult ticket = $3
Number of children = 1 u
Number of adults = 1 u + 60
Total cost of child tickets = 1 u x 1 = 1 u
Total cost of adult tickets = 3(1 u + 60) = 3 u + 180
Total cost of all the tickets
= 1 u + 3 u + 180
= 4 u + 180
4 u + 180 = 372
4 u = 372 - 180
4 u = 192
1 u = 192 ÷ 4 = 48
Number of child tickets = 48
Answer(s): 48
