$1 |
|
| Total value |
5 u + 415 |
1 u |
6 u + 415 |
Cost of 1 child ticket = $1
Cost of 1 adult ticket = $5
Number of children = 1 u
Number of adults = 1 u + 83
Total cost of child tickets = 1 u x 1 = 1 u
Total cost of adult tickets = 5(1 u + 83) = 5 u + 415
Total cost of all the tickets
= 1 u + 5 u + 415
= 6 u + 415
6 u + 415 = 583
6 u = 583 - 415
6 u = 168
1 u = 168 ÷ 6 = 28
Number of child tickets = 28
Answer(s): 28
