8 u + 464 |
1 u |
9 u + 464 |
Cost of 1 child ticket = $1
Cost of 1 adult ticket = $8
Number of children = 1 u
Number of adults = 1 u + 58
Total cost of child tickets = 1 u x 1 = 1 u
Total cost of adult tickets = 8(1 u + 58) = 8 u + 464
Total cost of all the tickets
= 1 u + 8 u + 464
= 9 u + 464
9 u + 464 = 770
9 u = 770 - 464
9 u = 306
1 u = 306 ÷ 9 = 34
Number of child tickets = 34
