6 u + 360 |
Cost of 1 child ticket = $1
Cost of 1 adult ticket = $5
Number of children = 1 u
Number of adults = 1 u + 72
Total cost of child tickets = 1 u x 1 = 1 u
Total cost of adult tickets = 5(1 u + 72) = 5 u + 360
Total cost of all the tickets
= 1 u + 5 u + 360
= 6 u + 360
6 u + 360 = 624
6 u = 624 - 360
6 u = 264
1 u = 264 ÷ 6 = 44
Number of child tickets = 44
Answer(s): 44
