7 u + 396 |
Cost of 1 child ticket = $1
Cost of 1 adult ticket = $6
Number of children = 1 u
Number of adults = 1 u + 66
Total cost of child tickets = 1 u x 1 = 1 u
Total cost of adult tickets = 6(1 u + 66) = 6 u + 396
Total cost of all the tickets
= 1 u + 6 u + 396
= 7 u + 396
7 u + 396 = 634
7 u = 634 - 396
7 u = 238
1 u = 238 ÷ 7 = 34
Number of child tickets = 34
Answer(s): 34
