7 u + 700 |
1 u |
8 u + 700 |
Cost of 1 child ticket = $1
Cost of 1 adult ticket = $7
Number of children = 1 u
Number of adults = 1 u + 100
Total cost of child tickets = 1 u x 1 = 1 u
Total cost of adult tickets = 7(1 u + 100) = 7 u + 700
Total cost of all the tickets
= 1 u + 7 u + 700
= 8 u + 700
8 u + 700 = 908
8 u = 908 - 700
8 u = 208
1 u = 208 ÷ 8 = 26
Number of child tickets = 26
Answer(s): 26
