$1 |

| Total value |
5 u + 470 |
1 u |
6 u + 470 |
Cost of 1 child ticket = $1
Cost of 1 adult ticket = $5
Number of children = 1 u
Number of adults = 1 u + 94
Total cost of child tickets = 1 u x 1 = 1 u
Total cost of adult tickets = 5(1 u + 94) = 5 u + 470
Total cost of all the tickets
= 1 u + 5 u + 470
= 6 u + 470
6 u + 470 = 620
6 u = 620 - 470
6 u = 150
1 u = 150 ÷ 6 = 25
Number of child tickets = 25
Answer(s): 25
