1 u + 50 |
1 u |
2 u |
| Value |
$4 |
$1 |
|
| Total value |
4 u + 200 |
1 u |
5 u + 200 |
Cost of 1 child ticket = $1
Cost of 1 adult ticket = $4
Number of children = 1 u
Number of adults = 1 u + 50
Total cost of child tickets = 1 u x 1 = 1 u
Total cost of adult tickets = 4(1 u + 50) = 4 u + 200
Total cost of all the tickets
= 1 u + 4 u + 200
= 5 u + 200
5 u + 200 = 340
5 u = 340 - 200
5 u = 140
1 u = 140 ÷ 5 = 28
Number of child tickets = 28
Answer(s): 28
