1 u + 65 |
1 u |
2 u |
| Value |
$4 |
$1 |
|
| Total value |
4 u + 260 |
1 u |
5 u + 260 |
Cost of 1 child ticket = $1
Cost of 1 adult ticket = $4
Number of children = 1 u
Number of adults = 1 u + 65
Total cost of child tickets = 1 u x 1 = 1 u
Total cost of adult tickets = 4(1 u + 65) = 4 u + 260
Total cost of all the tickets
= 1 u + 4 u + 260
= 5 u + 260
5 u + 260 = 445
5 u = 445 - 260
5 u = 185
1 u = 185 ÷ 5 = 37
Number of child tickets = 37
Answer(s): 37
