4 u + 324 |
1 u |
5 u + 324 |
Cost of 1 child ticket = $1
Cost of 1 adult ticket = $4
Number of children = 1 u
Number of adults = 1 u + 81
Total cost of child tickets = 1 u x 1 = 1 u
Total cost of adult tickets = 4(1 u + 81) = 4 u + 324
Total cost of all the tickets
= 1 u + 4 u + 324
= 5 u + 324
5 u + 324 = 444
5 u = 444 - 324
5 u = 120
1 u = 120 ÷ 5 = 24
Number of child tickets = 24
Answer(s): 24
