| Total value |
8 u + 704 |
1 u |
9 u + 704 |
Cost of 1 child ticket = $1
Cost of 1 adult ticket = $8
Number of children = 1 u
Number of adults = 1 u + 88
Total cost of child tickets = 1 u x 1 = 1 u
Total cost of adult tickets = 8(1 u + 88) = 8 u + 704
Total cost of all the tickets
= 1 u + 8 u + 704
= 9 u + 704
9 u + 704 = 1073
9 u = 1073 - 704
9 u = 369
1 u = 369 ÷ 9 = 41
Number of child tickets = 41
Answer(s): 41
